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.
