New features of the HP E1432A/HP E1433A software

The following features have been added to the HP E1432A/HP E1433A software since the previous edition of this manual. These and other features are documented in the online Function Reference. For more information look in the Function Reference entries for the functions that are used by the feature.

Auto range

Auto range calculates the best range for each channel so that the signal is full scale but not overloaded. Auto range works only while the measurement is running.

Averaging

Averaging can be done for resampling measurements on frequency or order data. It uses the function hpe1432_setAvgMode. You can set several averaging modes: RMS averaging, linear averaging, exponential averaging, or peak hold averaging.

Continuous re-sampled data

Continuous re-sampling forces the blocks of data to be contiguous, with no gaps between them. It uses the existing function hpe1432_setArmMode. (Without continuous re-sampling, each block of data follows the previous block after some interval, depending on the next trigger event.

Fast span or range change

You can now change the span or range while the measurement is running, using the existing functions hpe1432_setSpan or hpe1432_setRange. Previously if you sent the command while a measurement was running, it would wait until the next measurement. Now it will change the span or range when the command is sent.

Time arming

This uses a new function hpe1432_setArmTimeInterval. It allows you to specify a time interval for arming. For example you could set it to get a block of data every second.

Weighting filters (HP E1433A only)

For the HP E1433A, you can set any of three weighting filters (A-weighting, B-weighting, or C-weighting). This feature uses the function hpe1432_setWeighting.
