Chapter 4, Description of Fields
Fields
Antenna In
This field is used to indicate losses or gains between the ANTENNA IN port and
the device-under-test.
Enter a positive value to indicate a gain (such as an amplifier). The Spectrum
Analyzer’s marker level (
Lvl) measurement is automatically reduced by that
amount. The Spectrum Analyzer’s
Ref Level is automatically decreased by the
same amount, so the trace position does not appear to change.
Enter a negative value to indicate a loss (such as cable loss). The Spectrum
Analyzer Marker’s Level (
Lvl) measurement is automatically increased by that
amount. The Spectrum Analyzer’s
Ref Level is automatically increased by the
same amount, so the trace position does not appear to change.
This field is only used when the
RF Level Offset field is set to On.

Screens Where Field is Present
CONFIGURE
Arm
This field triggers a single measurement. It is only displayed when the Meas
Cntl
field is set to Single. This field is not updated to show the Meas Cntl mode
when the Test Set is in remote operating mode.
GPIB Examples
“TRIG:MODE:RETR SINGle”
sets the remote operation trigger mode to “Single”.
“TRIGger:IMMediate”
triggers all active measurements.
Operating Considerations
Sending a command to trigger a measurement will re-start a measurement if there
is one in progress.
When any of the CDMA screens are selected, all measurements are active. This
eliminates the need to display specific screens to get measurement results.
