Name

Description

Function

Acquire Measurements

Initiates new acquisition from the measurement buffer system (if acquisition is in the stopped state). Blocks until the number of measurements for each enabled channel is equal to count, or a time out has occurred.

Function

Advance Read Index

Send a command to the meter to notify it the user is done reading and to advance the read index.

Function

Clear Buffer

Sends a command to the power meter to clear all buffered readings. This method does not clear cached measurements accessible through GetAverageMeasurements, etc.

Function

Clear Measurements

Clears cached average, min, max, duration, start time, and sequence number measurements.

Function

Get Buffered Average Measurements

Get the average power measurements that were captured during the last call to AcquireMeasurements.

Function

Get Buffered Measurements Available

Gets the number of measurements available in the power meter's internal buffer. Note: The number of readings that have been acquired may be more or less.

Function

Get Duration

Set/get the duration samples are captured during each timed mode acquisiton.

Function

Get Durations

Get the duration entries in seconds that were captured during the last call to AcquireMeasurements.

Function

Get Gate Mode

Each Buffer Entry is controlled by a "buffer gate" that defines the start and end of the entry time interval. The gate signal may be internally or externally generated in several different ways.

Function

Get Max Measurements

Get the maximum power measurements that were captured during the last call to AcquireMeasurements.

Function

Get Meas Buff Enabled

Enable or disable the measurement buffer. Disabling the measurement buffer enables modulated/CW measurements. Conversely, enabling it disables modulated/CW measurements.

Function

Get Measurements Available

Get the number of measurement entries available that were captured during the last call to AcquireMeasurements.

Function

Get Min Measurements

Get the minimum power measurements that were captured during the last call to AcquireMeasurements.

Function

Get Over Ran

Flag indicating whether the power meter's internal buffer filled up before beign emptied.

Function

Get Period

Set/get the period each timed mode acquisition is started.

Function

Get Return Count

Set/get the return count for each measurement query.

Function

Get Sequence Numbers

Get the sequence number entries that were captured during the last call to AcquireMeasurements.

Function

Get Session Count

Set/get the count of elements for this measurement buffer session. Set to 0 for the meter to continuously acquire measurements.

Function

Get Start Mode

Mode used to start acquisition of buffer entries.

Function

Get Start Times

Get the start time entries in seconds that were captured during the last call to AcquireMeasurements.

Function

Get Timed Out

Check if the last measurement buffer session timed out.

Function

Get Write Protection

Set true to allow the measurement buffer to overwrite members that have not been read by the user.

Function

Query Average Measurements

Query the power meter for all buffered average power measurements.

Function

Query Durations

Query the power meter for all buffered measurement durations in seconds.

Function

Query Max Measurements

Query the power meter for all buffered maximum power measurements.

Function

Query Min Measurements

Query the power meter for all buffered minimum power measurements.

Function

Query Sequence Numbers

Query the power meter for all buffered sequence numbers.

Function

Query Start Times

Query the power meter for all buffered start times in seconds.

Function

Set Duration

Set/get the duration samples are captured during each timed mode acquisiton.

Function

Set Gate Mode

Each Buffer Entry is controlled by a "buffer gate" that defines the start and end of the entry time interval. The gate signal may be internally or externally generated in several different ways.

Function

Set Meas Buff Enabled

Enable or disable the measurement buffer. Disabling the measurement buffer enables modulated/CW measurements. Conversely, enabling it disables modulated/CW measurements.

Function

Set Period

Set/get the period each timed mode acquisition is started.

Function

Set Return Count

Set/get the return count for each measurement query.

Function

Set Session Count

Set/get the count of elements for this measurement buffer session. Set to 0 for the meter to continuously acquire measurements.

Function

Set Start Mode

Mode used to start acquisition of buffer entries.

Function

Set Write Protection

Set true to allow the measurement buffer to overwrite members that have not been read by the user.

Function

Start Acquisition

Starts measurement buffer acquisition. This method allows the user to send a command to the power meter to begin buffering measurements without waiting for all measurements to be completed. Alternately, you can call the AcquireReadings method to start buffering measurements and wait for them to be read from the meter.

Function

Stop Acquisition

Sends a command to stop the measurement buffer from acquiring readings.
