4530 Series RF Power Meter Operation
Main Menu > Channel 1 | 2 > Params > Impedance
Characteristic impedance is used only for voltage to power conversions. This is useful for calculating and
displaying power from a voltage measured across a load impedance using a voltage probe.
Range: 10.0 to 2500.0 ohms
Default: 50.0 ohms
Remote Command: SENSe:IMPEDance <n>
Main Menu > Channel 1 | 2 > Display > VertSpan
Select the vertical sensitivity for the full height of the graph display in a 1-2-5 scaling sequence. Note that the
vertical span setting controls only the graph display presentation, and has no effect on measurement. Full
dynamic range measurements are always availably even if the trace is off scale.
Range: 0.1 to 100 dB in a 1-2-5 sequence (log units)
1nW to 1MW in a 1-2-5 sequence (watts)
1nV to 1MV in a 1-2-5 sequence (volts)
1% to 10000% in a 1-2-5 sequence (ratiometric mode with linear units)
Default: 100 dB (log units)
Remote Command: DISPlay:TRACe:{LOGSPAN | LINSPAN | PCTSPAN} <n>
Main Menu > Channel 1 | 2 > Display > VertCntr
Set the power or voltage level that corresponds to the center of the display. Note that the vertical center
setting controls only the graph display presentation, and has no effect on measurement. Full dynamic range
measurements are always availably even if the trace is off scale.
Range: -100.00 to 100.00 dBm (log units)
1nW to 1MW (watts)
1nV to 1MV (volts)
0.01 to 9999.99% (ratiometric mode with linear units)
Default: 0dBm (log units)
Remote Command: DISPlay:TRACe:{LOGCNTR | LINCNTR | PCTCNTR} <n>
Main Menu > Channel 1 | 2 > Display > Units
Select the measurement units for both the display and remote interface. Note that some display settings have
different sets of values depending on the measurement units selected.
Log-dBm Power in dB relative to 1 milliwatt (Default)
Lin-Watts Power in watts (calculated from voltage and user-supplied impedance for voltage
probes)
Lin-Volts RF Voltage (calculated from power and sensor impedance for power sensors)
Log-dBV Voltage in dB relative to 1 volt
Log-dBmV Voltage in dB relative to 1 millivolt
Log-dBuV Voltage in dB relative to 1 microvolt
VSWR Calculated VSWR (ratiometric measurements only)
Remote Command: CALCulate1:UNITs <DBM, WATTS, VOLTS, DBV, DBMV, DBUV, VSWR>
