In the MS272xB trace menu, what is the purpose of minimum hold?

Minimum hold is very handy when looking for signals near the noise floor. A discrete signal will stay put while the surrounding noise level will drop as every display point shows the smallest level that was detected. The displayed noise can drop more than 10 dB after a few sweeps.

I want to copy several hundred measurements from my MS272xB or MT8222A internal memory to transfer them to a PC, what is the fastest way to do it?

The fastest way is to copy them all to a Compact Flash module and then copy them into your computer using a Compact Flash reader. We've found that the Sandisk Ultra II CF modules are about 3x faster then their slower brethren. If you don't have a CF reader, it may be worth the expense to buy one. You can use a USB memory stick, but they aren't as fast as CF. The fastest we've used is a Sandisk Titanium USB stick - but it is less than one-forth the speed of a fast CF module. USB sticks are slower than CF because of the parallel data architecture of CF compared to USB.

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.

What is the difference between a normal marker and a counter marker on the MS272xB and MT8222A?

There are 551 display points across the screen. During the normal course of measurements there are several measurements taken at differing frequencies for each display point. When a normal marker is being used the frequency at the center of each display point is shown. When counter marker is selected the frequency at which the instrument was tuned when it made the largest measurement is displayed.

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.

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.

On my MS272XB how do I determine if a signal I see on the screen is real one, or a spurious response?

An internally generated spurious signal will be at a fixed frequency. Put a marker on the signal and center the signal on the display by using "Marker Freq to Center". Zoom in on the signal by reducing the span. If the span was very wide to begin with, you may need to recenter the signal once when the span becomes significantly narrower. An internally generated spurious signal will stay centered on the display as the span becomes very narrow because it is tied to the instrument's reference oscillator frequency.

In the past I have used a S332D with Option 29, Internal Power Meter. I am now using a MS2721B however I do not see an option for Internal Power Meter. Is this available on the MS272XB Spectrum Masters?

Internal Power Meter is not available on the MS272XB Spectrum Master series.  You can measure power up to 6 GHz with Option 19 (High Accuracy power meter) and a PSN50 sensor.

I'm unable to remove the battery cover on my MS272xB or MT8222A. What should I do?

Sometimes the covers are difficult to remove for the first time. Insert a flat-blade screwdriver to the gap between the cover and the case and slightly rotate the screwdriver to pop off the cover. You should only have to do this once.

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.

How can I retrieve the GPS location information from my MS272xB?

There is a SCPI command :FETCH:GPS? that returns four comma delimited parameters: <fixstatus>, <date/time>, <latitude>, <longitude>. The <fix status> field will be either “GOOD FIX” or “NO FIX” depending on whether or not the GPS receiver is currently calculating position data. If “NO FIX” is the value of the <fixstatus> field then no data follows.

Both <latitude> and <longitude> fields are expressed in radians. A negative latitude corresponds to a “South” reading. A negative longitude value corresponds to a “West” reading.

Does the GPS receiver in the MS272xB and MT8222A with Option 31 use WAAS to enhance accuracy?

No, the Wide Area Augmentation System (WAAS) is a navigation aid intended to let aircraft rely on GPS for all phases of flight, including precision airport approaches. Since determinng the location of a base station generally doesn't require that level of precision WAAS is not used.

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.

I would like a tracking generator for my MS2724B. Can the MS2721B tracking generator be added to the MS2723B or MS2724B?

No, the internal designs are different enough so that the MS2721B tracking generator is not compatible with the MS2723B or the MS2724B.

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.

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.

What is the 1 dB gain compression value for the MS2721B?

With the preamplifier off, 1 dB gain compression is 0 to +5 dBm typical. The lower power level is at the low frequency end.
With the preamplifier on, 1 dB compression is -25 to -20 dBm typical. Again with the lower power level and the low frequency end.

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.

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.

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.
