Command: *GWL Answer: PWC: 1064<CR><LF>
4.6.4. Control
*ANT - Set Anticipation
This command is used to enable or disable the anticipation processing when the device is reading from a
wattmeter. The anticipation is a software-based acceleration algorithm that provides faster readings using
the detector’s calibration.
Command Parameters Answer
ANT 1: On
0: Off None
Default: On
Example
The following example sets the anticipation On.
Command: *ANT1 Answer:
*GAN - Get Anticipation Status
This command returns the anticipation status. If the anticipation is not available, it will always be at “off”.
Command Parameters Answer
GAN None 1: On
0: Off
Example
Command: *GAN Answer: Anticipation: 0<CR><LF>
*AVG - Noise Suppression Averaging
Sets the sampling size of the noise suppression.
For pyroelectric detectors and UM detectors only .
The joulemeter mode has a special proprietary algorithm that can lower the noise-induced error when
reading low energy levels, or energy readings of any level with noise present. This feature greatly reduces
the effect of noise on the peak-to-peak measurement in joulemeter mode. The monitor will need to measure
the number of pulses selected in the Sampling Size before the algorithm will settle to the noise suppressed
value. Once the readings have stabilized, any subsequent reading will be stable until the Sampling Size is
changed. The system will then stabilize to the new value. Larger sampling sizes will result in more noise
suppression. Noise suppression works best with the external trigger. This function will greatly improve the
accuracy of the lowest scale or in any scale when used in a noisy environment.
The parameter must consist of exactly 3 digits.
