GPIB OPERATION ML24XXA NATIVE COMMANDS

AVGLL Auto low level averaging SENSOR

Syntax: AVGLL <s>,<mode>

s:A or B

mode: OFF LOW MEDIUM HIGH

Remarks: Sets the low level averaging window for the sensor. At resolution settings of 0.01 and 0.001dB, digital readouts may flicker due to the high reading rate of the ML2430A Series. Low level averaging applies a low pass filter to post-average data readings to achieve a more stable front panel display without slowing down the response of the meter to larger changes in level. The three windows for LOW, MEDIUM and HIGH low level averaging are

± 0.01, 0.02, and 0.05 dB.

For example: When a LOW setting of low level averaging is applied while stepping from 0 dBm to –1 dBm, the meter displays the final reading within 0.01dB with no delay. The final settling of 0.01dB will settle over a short subsequent period of time, leading to a stable high resolution readout.

With a HIGH setting of low level averaging, the settling window is in- creased (up to approximately 0.05 dB) and the settling time is longer.

With low level averaging OFF, the meter displays the final reading instantly with no further settling observed. Any jitter due to noise is reflected in the displayed reading, which may be inconvenient for high resolution readings.

Example: AVGLL A,HIGH

String: AVGLL <S>,<MODE>

AVGM Manual Averaging SENSOR

Syntax: AVGM <s>

s:A or B

Remarks: Changes the averaging of the sensor to 'Moving' averaging mode from 'Auto' Averaging. The average number is set to the same value that the 'Auto' averaging mode was using internally. If the sensor is not presently in auto averaging mode, this command is ignored.
