Chapter 4, Description of Fields
Fields
Ref Level
Reference level sets the amplitude reference level for the top line of the display.
All signals displayed are referenced to this line. This field is displayed when the
Controls field is set to Main.
GPIB Example
“CSP:RLEV 0”
sets the reference level to 0 dBm.
Operating Considerations
The unit-of-measure for the reference can be changed as needed. For instance, 0
dBm, 0.224 V, 107.0 dBmV, and 0.00100 W can all be used to represent the same
level.

Ref Level (CDMA Swept Power Measurement)
This field sets the amount of the high value on the 40-dB vertical range of the
display.
GPIB Example
“CDMA:SWEPtpower:RLEVel ‘15’”
sets the reference level high value.
Operating Considerations
Enter a value here that represents the reference level of the mobile station before it
is ramped. This will allow the DSP to autorange and capture the trace correctly.
The selectable range is +35 to
−25 dBm. The default value is +5 dBm.
This value is also used to set the input path gain on the
Auxiliary menu Input
Atten
field.
