From the frequencies 250 - 320 MHz my MS2026A does not look correct. It has a saw tooth look between these frequencies. This was intermittent as a power off/on would fix it for a short time. Then I noticed the IF Cal is OFF warning.

Factory Calibration is OFF. Insure that the battery level is adequate for operation or that the temperature is within acceptable limits. Reset to factory defaults with either Factory Defaults, ESC+ON, or MASTER RESET, System + ON. Caution: Use of MASTER RESET, System + ON, will erase all user saved setups and measurement traces and return the unit to a factory default condition. If the error persists, then contact your Anritsu Service Center.

I am using a MS2036A. During OSLT 2 port calibration I am not asked to use the open, short and on the second the RF port. Is my calibration going to be valid?

Yes. Although you are doing a 2 port measurement RF power is only going from the RF port to the RF In port. The open and short calibration combined with the Load on RF out and RF in and the through calibration will calibrate the unit properly.

Why does the last octet of the subnet mask return to 0 regardless of what I set it to?

Certain versions of software for the Spectrum Master (MS2721B, MS2723B, and MS2724B), the VNA Master (MS2024A, MS2026A, MS2034A, and MS2036A) and the BTS Master (MT8222B) have an issue with the display of the last octet of the subnet mask.
 
In these versions of the software, if you set the last octet of the subnet mask to a value other than 0, then view the setting when the ethernet is NOT connected to another device, the last octet of the subnet mask will be displayed as 0.  However, the correct subnet mask is stored, and if you connect the ethernet connetion before powering up the tester, the subnet will be displayed correctly.

I would like to know the operating and storage temperature specifications for VNA Masters (MS2024/MS2026/MS2034/MS2036A).

Operating Temperature: -10 degree C to 55 degree C. Storage Temperature: -51 degree C to 71 degree C.

What is "Log Mag Dual Overlay" function and its use on the VNA Master?

Log Mag Dual Overlay will display both S11 and S21 on the VNA Master screen simultaneously overlaid on the same set of graticules. You get no choice of how to look at them – Log Mag only. S21 is the yellow trace, measured against the left-side graph scale. S11 is the blue trace measured against the right-side graph scale. The sweep will alternately update S11 and S21. It can not sweep both s-parameters simultaneously.  When Log Mag Dual Overlay is active, the Scale hard key menu will add an extra soft key that will toggle between S21 and S11 scale modification.  The features were added for those of our customers who spend a lot of time tuning filters and duplexers, and want to be able to watch both traces while tuning.

Will the InstaCal Calibration Module, ICN50, work on the MS2036A?

No.  The InstaCal Calibration Module, ICN50, will not work on the VNA Masters ( MS2024A, MS2026A, MS2034A, MS2036A) or the BTS Master (MT8222A).

What are the four S Paramaters?

S11 Forward Reflection represents the measurement in which the signal leaves port 1 and is reflected back to port 1.

S21 Forward Transmission represents the measurement in which the signal leaves port 1 and is transmitted to port 2.

S12  Reverse Transmission represents the measurement in which the signal leaves port 2 and is transmitted to port 1.

S22  Reverse Reflection represents the measurement in which the signal leaves port 2 and is reflected back to port 2.

Why does my MS2721B give me an input saturation warning when other instruments don't?

The MS272xB, MS271xB, MS2711D, MT8222A and MS20x6A are equipped with a broadband detector that is designed to sense signal levels at the input to the first mixer that may cause inaccurate measurements due to saturation. Most competitive instruments don't have a method to deliver such a warning and allow the user to take measurements that likely are inaccurate. These inaccuracies can include lower amplitude values and the generation of signal harmonics due to mixer saturation.

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

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

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.

Is there a rack mount kit available for handheld instruments?

There is a rack mount kit available for current models of handheld instruments. The part number is 66864. This kit can be used with the following models: S331E, S332E, S361E, S362E, MT8221B, MT8222B, MT8212E, MT8213E, S412E, MS2024B, MS2025B, MS2034B, MS2035B, MS2026C, MS2028C, MS2036C, MS2038C, MS2722C, MS2723C, MS2724C, MS2725C, MS2726C, MS2711E, MS2712E, MS2713E, and MS2721B
