[:SENSe]:AVErage:FERRor:COUNt n
[:SENSe]:AVErage:FERRor:COUNt?
Title
Frequency Error Average
Description
When count is greater than one, the frequency error value is averaged over past measurements. If count is one, then no averaging occurs.
If Count = N, and M is the number of measured values, then when M < N:
FE next = (FE1 + FE2 + … + FEN–1)/(N–1).
When M N:
FE next = [(N–1) * FE previous + FE new]/N
Note: This is commonly called a modified (or running) moving average.

Title
Coverage Mapping Thresholds
Description
The above commands set/return the threshold levels used in coverage mapping. There are five defined levels: Excellent, Very Good, Good, Fair and Poor. For each level, there is a threshold power that sets the lower boundary for that level. Setting the Excellent threshold to –100.0 dBm, for instance, means that measurement greater than –100.0 dBm will be considered excellent in the report and as display on the coverage map.
Thresholds are set as a comma separated list of power values in order from Excellent to Poor. No units are used, and when setting the threshold values, enclose the all five values in a single set of quote markers.
Examples
Sending: SENSe:OTA:MAPping:SSSPower:THREShold?
Returns: –107.0,–110.0,–114.0,–117.0,–120.0
Sending: SENSe:OTA:MAPping:SSSPower:THREShold “–100.0,–103.0,–104.5,–112.0,–118.0 “
Sets the S‑SS Power thresholds to:
Excellent: 100.0 dBm
Very Good: 103.0 dBm
Good: 104.5 dBm
Fair: 112.0 dBm
Poor: 118.0 dBm

[:SENSe]:POWer[:RF]:RANGe:AUTO {Boolean (default=1 [ON])}
[: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 uncoupled 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.
