[:SENSe]:PFail <test set>
[:SENSe]:PFail?
Title
PASS/FAIL Test Selection
Description
Selects the active test set to be used in subsequent PASS/FAIL measurements. The <test set> value must correspond to a test set that is defined in the test set list. To view the list on the instrument, go into the “Measurement” menu, press the “Pass/Fail Mode” key, and then press the “Select Pass/Fail Test” submenu. Alternatively, the list can be retrieved remotely and viewed using the Anritsu Master Software Tools. The <test set> argument is a 1-based index of the position of the desired Pass/Fail test set in the instrument’s current Pass/Fail test set list. For example, if the desired Pass/Fail test is the 3rd item on the list, then the value of the <test set> argument would be 3.
When using the query form of the command, the return value is the currently selected test set number. If there is not a valid test set selected, the return value is “-1” (negative 1).

[:SENSe]:POWer[:RF]:RANGe:AUTO OFF|ON|0|1
[:SENSe]:POWer[:RF]:RANGe:AUTO?
Title
Automatic Amplitude Range
Description
Sets the automatic amplitude range. Setting the value to ON or 1 will result in the amplitude range being coupled to the detected input signal level. Setting the value to OFF or 0 will result in the input attenuation being un-coupled from the input signal level. That is, changing the input signal level will not change the amplitude range. When this command is issued, the amplitude range itself will not change. The default value is ON. That is, sending :SENS:POW:RANG:AUTO is equivalent to sending :SENS:POW:RANG:AUTO ON.
Parameter
