4530 Series RF Power Meter Operation

Main Menu > Statisticl > TrmCount

Sets the terminal count (sample population size) for statistical mode acquisition. When the terminal count is

reached, the CDF is considered “complete”, and the instrument will halt acquisition if INITiate:CONTinuous

is set to OFF. If INITiate:CONTinuous is ON, sample acquisition will continue in the manner specified by the

TRIGger:CDF:DECImate setting.

Range: 2 to 4000 MegaSamples

Default: 4000 MegaSamples

Remote Command: TRIGger:CDF:COUNt <n>

Main Menu > Statisticl > TrmAction

Select the action to be taken when the Statistical Mode terminal count is reached.

Stop Stop sampling when the terminal count is reached. The measurement halts and no

further samples are added to the population. (Default)

Restart Clear the measurement and restart acquisition of a new sample population once

the terminal count is reached. This setting is used when the signal changes and

old data must be periodically flushed to maintain valid statistics. Note that it may

take several seconds after each restart before enough samples are taken for a

statistically significant population.

Decimate Decimate the current sample population (divide all sample counts in half), and

continue adding new samples to the same population. The effect is to “decay” the

old information, and more heavily weight the new information. This provides a

technique for coping with changing signals without the invalid interval associated

with the Restart setting, but the setting should be used with caution, as it may take

some time for all old data to be decimated away, depending on the Terminal Count

setting.

Remote Command: INITiate:CONTinuous <OFF, ON> for Stop or Continous running

TRIGger:CDF:DECimate <OFF, ON> to select between Restart and Decimate.

3.11.6 Calibratr Menu.

The Calibratr Menu is used to control both the internal, 50 MHz RF calibrator, and an optional, external 1 GHz

accessory calibrator (Model 2530). Both calibrators may be used as precision RF reference levels for testing

or measurements. The internal calibrator is CW only, while the external calibrator may be pulse modulated

using either a built-in pulse generator, or via a rear-panel BNC pulse input. Note that this menu does not

contain any items related to sensor calibration - it is only for controlling the calibrator for use as a signal

source. For sensor calibration information, refer to Section 3.10 of this manual.
