UNIT
dBm
dBuV
dBuA
dBpW
dBpT
The UNIT key opens a submenu in which the desired units
for the level axis can be selected.
Default setting is dBµV.
In general, a receiver measures the signal voltage at the RF
input. The level display is calibrated in rms values of an
unmodulated sinewave signal. Via the known input
resistance of 50 Ω a conversion can be made to other units.
The units dBm, dBµA, dBpW, and dBpT are directly
convertible.
IEC/IEEE-bus command CALC:UNIT:POW DBM
RF INPUT
AC DC
The RF INPUT AC/DC softkey switches between AC and DC coupling of the
instrument input.
IEC/IEEE bus commands INP:COUP AC
GRID RANGE
LOG MANUAL
The GRID RANGE LOG MANUAL softkey activates the entry of the level
display range for the scan diagram.
The display ranges go from 10 to 200 dB in 10-dB steps. Invalid entries are
rounded off to the nearest valid value.
IEC/IEEE bus commands DISP:WIND:TRAC:Y:SPAC LOG
DISP:WIND:TRAC:Y 120DB
GRID
MIN LEVEL
The GRID MIN LEVEL softkey activates the entry of the minimum level of the
display range. Allowed values are:
- 200 ≤ GRID MIN LEVEL ≤ + 200 dB - GRID RANGE
