Do any of your spectrum analyzers have a quasi-peak detect function (to use for FCC testing)?

Yes, the MS2721B Spectrum Analyzer has quasi-peak detection function. Resolution bandwidth is 200 Hz, 9 kHz, and 120 KHz when quasi-peak detector is selected.

How can I rename saved measurements in my MS2721B?

The instrument doesn't include a mechanism to change file names by itself since it isn't usually used for long-term storage of measurements. However, by using Master Software Tools, you can connect to the instrument and open the file and rename it. Then use the | Sync | Upload Active Window | to put the renamed file back into the instrument. The file with the old name will still be in the instrument so if desired, you can delete the old one.

I want to easily step from channel to channel using my MS2721B spectrum analyzer. How can I do that?

In the frequency menu there is a soft key called "Freq Step".  It has a default value of 1 MHz.You can change that value to anything you want to a resolution of 1 Hz. Once you have that value set to your channel spacing, set the center frequency to your first channel. Then use the up and down arrows to move in the step size you entered. Make sure the center frequency is the active parameter before pressing the up or down arrow. You can also change a parameter you didn't intend. The Frequency step can also be used to change start frequency and stop frequency.

Can I make a return loss measurement with the MS2721B's tracking generator?

Yes, an external bridge is needed to make the measurement. Connect the bridge between the TG output and the spectrum analyzer input. Put a short circuit on the test port. In the Tracking Generator menu press the "S21 Insertion Loss" soft key followed by the "Normalize Off On" soft key to do a normalization sweep. You should end up with a flat line at the 0 dB point on the relative scale that will be displayed on the right side of the screen. Replace the short circuit with the device to be tested and directly read the return loss results in dB.

Can I measure phase noise with my MS2721B spectrum analyzer?

Yes, with limitations. The oscillator being measured must have worse phase noise than the instrument does. The measurement of phase noise is done in units of dBc/Hz at a particular offset from the carrier. Set a reference marker on the peak of the carrier and turn on the associated delta marker. Set the delta marker offset to the point at which you want to measure and change the marker type to "Marker Noise".  The delta marker value will show the measurement in dB, which is dB below the carrier amplitude normalized to a 1 Hz bandwidth. Use a trace averaging value of at least 20 to minimize amplitude flucuations.

I have a MS2721A Spectrum Master and I want to set my MAX Hold. How do I set It?

Press shift and trace keys, then select Trace A softkey menu, then select Max-Hold softkey.

The signal standard list in my MS2721B doesn't have a signal standard that I want to use. What does it take to add it to the instrument?

Master Software Tools, a software product that ships with each instrument has the capability to add entries to the signal standard table. With the instrument connected to MST you can open the signal standard for editing by pressing | Sync | Download Signal Standards | SPA/IA/CS Signal Standards |. The MST User's Guide provides details about how to add a standard. If the missing standard is one that would be generally useful, Anritsu would appreciate receiving details of the missing standard.

On the tracking generator in the MS2721B, what is the maximum frequency error between the tracking generators output frequency and the center frequency of the spectrum analyzer?

The tracking generator frequency is generated from the same local oscillators that tune the spectrum analyzer. Consequently the frequency error between the two is zero. They are always on the same frequency.

Are there any plans to add an over the air option to demodulate 8VSBA on my MS2721B?

There are no plans to support ATSC-M/H standards at this time.

Does the MS2721B support CDMA 450MHz band?

Yes it is supported.  You can enter the frequency or you can select the signal standard and enter the channel number. 
Here are the signal standards:

CDMA2000 Class 5 (NMT-450-20 kHz)- Uplink

CDMA2000 Class 5 (NMT-450-20 kHz)- Downlink

CDMA2000 Class 5 (NMT-450-25 kHz)- Uplink

CDMA2000 Class 5 (NMT-450-25 kHz)- Downlink



I am writing a control program to work with my MS2721B. The quasi-peak command does not exist in the Programming Manual, nor can I retrieve it when I query using the :sens:det:func. Is this command available?

As of June 2009 the Remote commands for Quasi-Peak detection are being developed. They are not currently available. Expected date for these commands does not have an official target but we hope to have them by end of August, 2009.

Will an MS2721B with options 078 and 009 DVB-T functions work on COFDM DVB-T 6 MHz signal transmission in USA?

Option 78 provides SFN measurements on a DVB-T/H SFN network to measure multi-path related issues. For modulation analysis and RF measurements, Option 64 is required, which does support 6 MHz DVB-T bandwidth. We've only heard of some trial DVB networks in the US which are no longer operational. However, please note that ATSC is the digital broadcast standard in the US.

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.
