Signal Quality Analyzer-R MP1900A - 32G/64G NRZ/PAM4 Signal Integrity Test Solution

Data center and network traffic volumes are increasing exponentially as mobile networks start upgrading to 5G and ‘Big Data’ applications become popular. As a consequence, physical-layer devices are required to support faster transmission speeds, larger data capacities, and assured signal quality, in turn making signal integrity analysis ever more important. To meet these needs, Anritsu has implemented more accurate signal integrity tests, such as bit error rate (BER) measurements, crosstalk tests, Jitter Tolerance tests, etc., in its MP1900A test solution for 32G/64G NRZ/PAM4.

I've recently upgraded the firmware on my S331D and now under the DTF, I see an option for Optical. What is that?

The S331D when upgraded to Version 5.23 firmware or later has the internal capability to make Optical Distance To Fault measurements. An external Optical Distance to Fault Module is also needed to make the Optical DTF measurement. This part number is ODTF-1.

How many electrical channels can be tested on BitMaster MP1026A?

Two electrical channels can be tested.

Test There is a lot of concern about loss and reflections in the cable run to the antenna. Why don't the radio MFGs just make transmitters with more power?

The FCC regulates how much output power of any given transmitter. Since this is a fixed quantity, the system designers are forced to squeeze out every bit of performance out of the entire system.

We have a requirement for 2 CW RF microwave signals to be applied 90 degrees out of phase with each other into either end of a device under test. How can this be achieved?

This can be achieved with a pair of MG369XB's with the low band option (either option 4 or 5) and the Phase Tracking Special, SM5815. With this special the phase difference between the synthesizers can be set either from the front panel or programmed over GPIB.

How do I get my MS2721B to use a manual ethernet address after I enter one?

After you enter the ethernet address you want to use (i.e. 10.0.0.2) you must restart the unit on a live ethernet connection. You can use the crossover cable to connect to your computer's ethernet port as a live port, but only if you are assigning an address. If you use the DHCP (dynamic host control protocol), you must hook to a live ethernet connection that allows for DHCP requests.

The MA2474D specifies a "rise time" of 4 us at 0 dBm room temperature but gives no definition. Can you define it?

Rise time is defined as, the time interval necessary for the power sensor to rise from 10% to 90% of the reading when the signal rises instantaneously from zero (no power) to 1 mW (0 dBm).

What are the differences between the 37000C and 37000D? Should I upgrade?

The decision to upgrade, of course, depends on what you hope to gain through the upgrade. One of the main differences is that the 37000D series supports LAN communication, whereas the 37000C does not. The 37000D has better system dynamic range than the 37000C The 37000D has new measurements not available on the 37000C: Mixer Measurements: Directly measure frequency translation devices utilizing the NxN multiple device solution utility. The NxN application provides an accurate method of measuring frequency translated devices, such as mixers, providing both magnitude and phase information and the unique ability to measure absolute phase (group) delay. By measuring the response characteristics of device pairs, the Lightning VNA will solve for device pairs and de-embed the characteristics. The NxN application module for mixer measurements includes capabilities for characterizing the IF path of frequency translation device measurements. The result is a real-time display of the de-embedding characteristics of the device under test. Embedding/De-embedding: Manipulate S2P networks to automatically remove fixtures and devices or add effects of a known structure. De-embedding is generally used for removal of test fixture contributions and other S2P networks from measurements. The de-embedding can be applied to a calibration and then stored for future measurements. Similarly, the Embedding function can be used to simulate matching circuits for optimizing amplifier designs or simply adding effects of a known structure to a measurement.

Which offset short should I use for insertion loss measurements on Waveguide cable...the 1/8 offset short or the 3/8 offset short?

Either short is acceptable and will yield the same insertion loss.

I am using the Tripp Lite USB to serial adapter. I have verified the adapter is installed properly and the adapter shows up on Com 4 on my PC under Ports (Com & LPT). The port setting is port 4 in HHST. I have all baud rates set correctly and I still get an error in serial communications after several seconds.

If you have a wireless device enabled on your PC or laptop this can interrupt the serial communication. Go to Network connections and verify your Wireless Network connection type LAN or high speed internet is disabled. Even it says disconnected you should disabled it. This has been known to help in cases where everything is set up properly. Wireless devices such as Palm Pilots can cause this also so disable all wireless devices that you use.

I am using a VISTA 64 bit operating system and Delorme USB to serial adapter and I cannot get HHST to work.

HHST is compatible with VISTA 32 bit operating systems but not with VISTA 64 bit OS. Also per Delorme their USB to serial adapter is not compatible with VISTA 32 or 64.

On the S251C, can you save the power monitor measurements (option 5) by using the "Save Display" function?

No, the sitemaster "C" models and below will not save any power monitor (option 5) measurements. You can use this function on the "D" model sitemasters i.e. S311D/S312D, S331D/S332D, S810D/S820D, and MS2711D.

Can I sweep an antenna with a TMAS on the line?

No. The majority of TMAS for cellular antennas will block the RF signal from the Site Master so the sweeping signal will only go as far as the TMAS and not reach the antenna.

Can I sweep antennas close to another RF source?

Yes but you need to be very careful that the RF from another Source is not going to exceed the 20 dBm max on the RF port. Power in excess of 20 dBm can result in damage to the unit.

Can a .csv file that was converted from a .vna file of a VNA master be converted back to .vna using Master Software Tools?

No. If someone sends you a .csv file MST cannot be used to convert it back to a .vna file to be opened in MST.

How do I calculate Noise Power density (dBm/Hz) from a measurement made with the MS2711D or MS272x spectrum analyzer?

On the instrument, use a Noise Marker. If you have a captured trace (in dBm) that you want to convert to dBm/Hz, use the following formula: dBm/Hz = dBm - 10 * log(1.03 * RBW)

Can I use the C/I (carrier to interference ratio) to make SINAD measurements on a narrow-band FM signal?

No, the C/I measurement is intended for use when measuring Wi-Fi (802.11b,g and a) signals. The measurement makes certain assumptions about the nature of the Wi-Fi signal being measured and how it is affected by various types of interferers.

When I turn on Marker Noise, the detector changes to RMS, why is that?

The RMS detector is the best choice for noise measurements as it provides unbiased averaging of the signal. This gives a stable answer (because of the averaging) and gives the correct answer (because it is "unbiased"). Contrast this to the peak detector, where the answer continually grows over time, and the Sample detector, which provides no averaging

When do I use the Negative (peak) detector?

This is most useful with a zero-span display, when looking for dropouts in a signal.

When do I use the Peak detector?

This is the default detector for most measurements and is good for measuring CW signals, or for when you want to catch a transient. The peak detector gives a good overall picture of the spectrum but it’s not very good for measuring noise or modulated signals, as the peak of these signals is not well defined.

When do I use the Quasi-peak detector?

The Quasi-peak detector was designed to mimic the response of the human ear to interference and is used for making EMC (Electro-Magnetic Compatibility) measurements. The sweep time is quite slow when using this detector, so it is generally used only when making EMC measurements.
