I wired my handheld tester to my laptop, then I configured the ethernet settings accordingly, but was unable to make a connection. Is there more that I must do?

There are two things to keep in mind when using a LAN remote connection to the handheld testers:   1)  Changes made to the LAN settings do not take affect immediately - the power must be cycled for the changes to take affect.   2)  In an effort to maximize battery life, if no LAN connection is detected at power up, the LAN parts are turned off.  The only way to turn the LAN parts on is to turn the power off, connect to the LAN, and then turn power on.   So, in this case, where the LAN configuration was set and the connecting made, cycling power should allow a connection to be made.

Is it possible to set more than 5 segmented limit lines on MS2711D?

No, it is not possible to set more than 5 segmented limit lines on the MS2711D however we have other Handheld Spectrum Analyzers in which a limit line can consist of up to 40 segments. The model numbers are MS2721B, MS2723B, and MS2724B.

Are the display data points fixed in the MS2721A Spectrum Analyzer?

Yes, the display data points are fixed and are independent of the Frequency Span and Resolution Bandwidth. There are 551 display points when the instrument is in the normal screen display. By selecting the Trace Fullscreen (On) feature the display point count increases to 661.

What is the memory (Internal Flash Memory and EEPROM) clearing procedure for MS2724B Spectrum Master?

To erase all the user information that is stored in Internal Flash Memory and EEPROM, a master reset needs to be done on the instrument. Below is the master reset procedure.: 1. Turn the MS2724B. 2. Press the Shift button then the 8/System button. 3. Press the System Options soft key. 4. Press the Reset soft key. 5. Press the Master Reset soft key. 6. A dialog box will be displayed on the instruments screen warning that all settings will be returned to factory default values and all user files will be deleted. 7. Press the ENTER button to complete the master reset. 8. After several seconds (which can grow to several minutes if there are a very large number of measurements saved in the instrument) the instrument will reboot.

The MS272xB spectrum analyzer has several detector modes, how do I select the right one for my measurements?

 The available detectors are Peak, RMS, Negative, Sample and Quasi-peak. During sweeps, several measurements are made as slightly different frequencies for each display point. The peak detector displays the largest measured value for each display point, assuring that narrow spikes are not missed, the RMS detector calculates the RMS value of the several measurements for each display point and is best suited for measuring noise or noise-like signals, the negative detector displays the smallest measured value for each display point and is useful for making small signals near the noise floor more visible, the sample detector measures one point for each display point, making it the fastest detector. It is best suited for measuring broad signals where the value doesn't change rapidly with frequency; The quasi-peak detector is designed to meet CISPR requirements and is primarily used for EMC measurements in conjunction with special resolution bandwidths.

When I change the RBW or add input attenuation on my spectrum analyzer, the noise floor changes. Why?

The noise floor is caused by thermal noise generated in the instrument's circuits. When you select a wider resolution bandwidth, more noise comes through the filter and causes the noise floor to rise. When you add an internal input attenuator, modern instruments respond by increasing IF gain to maintain a constant reference level. The increased gain causes the noise floor to rise by an amount equal to the added attenuation.

I'm receiving a mixer saturation warning on my MS2721B, what does it mean and what can I do about it?

The MS272xB, MS271xB and MT8222A have a broadband detector before the first mixer. If the overall signal environment contains enough signal power to cause the mixer to compress the output signal, the mixer is "saturated". The fix is to reduce the amplitude of signals hitting the mixer by one or more of three approaches. If the signal is in-band, or is the signal you want to measure, turn off the preamplifier as a first step. If that doesn't reduce the amplitude enough, start adding input attenuation until the problem is resolved. If the signal is out-of-band, those two methods will work but a better way may be to insert a bandpass filter into the signal path to reduce the amplitude of out-of-band signals since that will preserve in-band sensitivity.

In the MS272xB frequency menu there is a soft key labeled "Channel --". What is it used for?

The channel value is used in conjunction with a signal standard such as CDMA to easily tune to a particular channel number associated with that channel. The user doesn't need to know the frequency of a particular channel, just the channel number for a particular air interface standard.

Can I use a MS272XB spectrum analyzer to measure noise figure?

Yes, with limitations. A spectrum analyzer can be used to measure the noise figure of a device with a significant amount of gain. The basic method is to start by measuring the noise floor of the instrument with a termination on the input. It is best to do this with attenuation set to 0 dB and the preamplifier turned on with a high averaging value (say, 100 or more). Turn on a marker along with a delta marker and set the marker type to FIXED. Next, connect the ampifier to be measured to the spectrum analyzer's input and move the termination to the input of the amplifier. Restart averaging and wait for the averaging to complete. The delta marker value will be the noise figure of the DUT plus the spectrum analyzer's noise figure divided by the gain of the amplifier. This method isn't suitable for low gain devices because of the "second stage contribution" of the spectrum analyzer.

What is the position accuracy of the GPS receiver in the MS272xB and MT8222A?

The position accuracy is approximately +/-6 meters under ideal conditions. This is not a specification, just characteristics. The actual accuracy depends on the number of satellite signals being received and their position in the sky. The more satellites and the farther apart they are in the sky, the better the accuracy. Our GPS receiver does not use the WAAS enhancement to GPS.

Can I enter the sweep time manually in Spectrum Analyzer mode?

Yes you can. You can go into the sweep menu (MT8222A, MS272XB) or "MEAS/DISP" menu (MS2711D, S332D, S312D, MT8212B) and select "Min Sweep Time" and enter the desired sweep time. If you enter a time that is faster than what the instrument is capable of then the instrument will change the sweep speed and default to whatever the instrument can do. For every measurement point, the instrument spends a certain time and if it is too fast, then it is measured again. This is why the actual sweep time is usually a little bit longer than the requested time. In zero span mode, the sweep times are exact.

What detection methods are available on MS2721B Spectrum Master?

The available detection methods are Peak, RMS, Negative, Sample and Quasi-peak.

How accurate is the positioning location of the GPS (opt 31)?

Approximately +/- 20 Meters but this is not specified.

What kind of reference oscillator is used in the MS2721B Spectrum Master?

An oven controlled crystal oscillator (OCXO) is the reference oscillator that is used in the MS2721B.

I am receiving a saturation warning on my MS272xB, MS271xB or MT8222A even though there are no large signals on the screen. Why is that happening and what can I do about it?

The presence of large signals, even if they are outside of the span range to which the instrument is set can cause mixer saturation and generate a warning so the user knows that measurement accuracy may be compromised. Increase input attenuation to reduce the amplitude of the signal into the instrument's circuits.

I want to create a spectral mask in my MS272xB or MT8222A that I can re-use at different frequencies. How do I do that?

While you are creating a limit line (aka spectral mask) set the limit line type to "Relative" in the Limit Advanced menu. Save the limit line with the name of your choice. When you recall that limit line it will be set to whatever the center frequency of the instrument is. If you saved a limit line as an Absolute limit line it will be recalled to the frequency at which it was created. If that is your case, go to the Limit Move menu and press the "Move Limit to Current Center Freq" soft key.

If I am using a resolution bandwidth that is very narrow compared to the span, will I miss some frequencies as the instrument sweeps?

For all detector types except Sample, the instrument makes enough measurements for each display point that there are no gaps in the frequency coverage. The Sample detector only makes one measurement per display point so gaps do occur if the resolution bandwidth is less than 1/551 of the span.

The noise floor of my MS272xB or MT8222A isn't flat, does that mean that measurements will be inaccurate?

No, the instrument is calibrated on the production line to make accurate measurements of signals. Variations in the noise floor merely show changes in the sensitivity of the instrument, not in the accuracy.

Do we still need to buy Option 19 to use the MA24106A with the instrument?

Yes - you need Option 19 to use the MA24106A sensor with the Spectrum Master, VNA Master, BTS Master, and Economy Spectrum Analyzer (MS271xB). The software that is included with the purchase of the MA24106A is used to connect the sensor to a PC.

There are several detector choices in my MS272xB, MS271xB and MT8222A. How do I decide which one to use?

Use the Peak detector most of the time. This choice displays the largest measured value for each of the 551 display points. Use the RMS detector if you are measuring noise or noise-like signals such as a CDMA Bart's head. Use the Negative detector to display the smallest measured value for each display point. This is useful when attempting to pick out signals that are near the noise floor. Use the Sample detector when using the tracking generator. There is one measurement made for each display point. Use the Quasi-peak detector if you are doing EMC measurements following the CISPR standards.
