4530 Series RF Power Meter

Operation

3.11.2 Channel Menu.

The Channel menu contains items that affect a single measurement channel. The “channel” is a full measure-
ment path, starting at (and sometimes before) the sensor, and including data acquisition, processing of
measurements, and display of the processed information. The Model 4531 single channel power meter has
only a Channel 1 menu, while the dual-channel Model 4532 has separate menus for Channel 1 and Channel 2.

Main Menu > Channel 1 | 2 > MeasMode

Set or return the measurement mode of the selected channel. CW and MODULATED are continuous mea-
surement modes, PULSE is a triggered, oscilloscope-like mode, and CDF, CCDF and DIST are various presen-
tation formats of statistical mode, which gathers and analyzes a large number of samples over a relatively long
time interval.

Off

Disable measurement

Modulated

Measure the true average power of the applied signal. (Peak sensor default)

PulseMode

Measure power versus time of a triggered signal. (Peak sensors only)

Statistcl

Measure the CCDF, CDF or Distribution of the input signal. See Paragraph 3.11.5
for Statistical Mode Parameter Settings. (Peak sensors only)

Measure the CW input signal. (CW & Voltage sensor default)

Remote Command:

CALCulate:MODe

Main Menu > Channel 1 | 2 > Params > dB Offset

Set a constant measurement offset. Used to account for attenuators and couplers in the RF signal path. In the
main TEXT display, a small triangle (Delta) symbol will appear above the units if the offset is not set to zero.

Range:

-100.00 to 100.00 dB

Default:

0.00 dB

Remote Command

SENSe:CORRection:OFFset

Main Menu > Channel 1 | 2 > Params > Frequency

Set the frequency of the input signal. Causes frequency cal factor to be automatically calculated from sensor
EEPROM data and applied to the measurement.

Range:

0.001 to 110.000 GHz

Default:

0.050 GHz (CW sensor) or 1.000 GHz (peak sensor)

Remote Command:

SENSe:CORRection:FREQuency

Main Menu > Channel 1 | 2 > Params > Averaging

Set the number of traces averaged together in pulse mode to form the measurement result. Used to reduce
noise. Also known as “video averaging” on competitive peak power meters.

Range:

1 to 4096

Default:

Remote Command:

SENSe:AVERage
