Trace Mode (Normal/Average/Max Hold/Min Hold)

Specifies how successive traces are combined to produce the resulting display value. Setting the TYPE to NONE is the equivalent of setting the trace mode to “Normal->A” on the front panel. The displayed value for a point is the current measured value for that point. Setting the TYPE to SCALar is the equivalent of setting the trace mode to “Average->A” on the front panel. The displayed value for a point is the average of the last <integer> measured values where <integer> is set by [:SENSe]:AVERage:COUNt. Setting the TYPE to MAXimum is the equivalent of setting the trace mode to “Max Hold->A” on the front panel. The displayed value for a point is the maximum measured value for that point over sweeps. Setting the TYPE to MINimum is the equivalent of setting the trace mode to “Min Hold->A” on the front panel. The displayed value for a point is the minimum measured value for that point over sweeps.

Video Bandwidth Coupling

Sets the state of the coupling of the video bandwidth to the resolution bandwidth. Setting the value to ON or 1 will result in the video bandwidth being coupled to the resolution bandwidth. That is, when the resolution bandwidth changes, the video bandwidth changes. Setting the value to OFF or 0 will result in the video bandwidth being uncoupled from the resolution bandwidth. That is, changing the resolution bandwidth will not change the video bandwidth. When this command is issued, the video bandwidth setting itself will not change. The default value is ON. That is, sending :SENS:BAND:VID:AUTO is equivalent to sending :SENS:BAND:VID:AUTO ON.

That is, changing the span will not change the resolution bandwidth. When this command is issued, the resolution bandwidth setting itself will not change. The default value is ON.

Input Impedance

Sets the input impedance that is used for amplitude correction and conversion between units (dBm vs. dBV vs. Volts, etc.). If the value of <integer> is 50, no correction is performed. If the value of <integer> is 75, correction is done based on Anritsu adapter 12N50‑75B. To place the instrument in Other or offset mode, send a 2. Once in the “Other” mode, the command, [:SENSe]:CORRection:IMPedance[:INPut]:OFFSet, can be used to adjust the offset.

Detection Type

Sets the detection method for calculating each display point. Each display point represents several measurements. The detection type determines how the display point is derived from its associated measurements. POSitive Peak detection displays the maximum value of the associated measurements. RMS detection displays the average power of the associated measurements. NEGative Peak detection displays the minimum value of the associated measurements. SAMPle detection displays the “middle” point of those measurements associated with a display point. For example, if there are 3 measurement frequencies associated with a given display point, sample detection will display the value at the frequency of the second measurement point.

Field Strength Antenna

Selects an antenna from the antenna list to use for field strength measurement result calculations. The <antenna> argument is a 1‑based index of the position of the desired antenna in the instrument’s current antenna list. The list can be displayed on the instrument by choosing the “Antenna” submenu key in the “F Strength” menu. For example, if the desired antenna were the 3rd item on the antenna listing then the value of the <antenna> argument would be 3. Setting the <antenna> argument to 0 indicates that no antenna is selected.

The query form of this command will return the index of the currently‑selected antenna.
