HP 54620A - Using the:Digitize Command

Using the :DIGitize command
The :DIGitize command captures data that satisfyies the specifications set up
during analyzer configuration. When the digitize process is complete, the
acquisition is stopped. The captured data can then be measured by the
instrument or transferred to the controller for further analysis. The captured
data consists of two parts: the waveform data record and the preamble.
Ensure New Data is Collected
After changing the logic analyzer configuration, the waveform buffers are
cleared. Before running a measurement, send the DIGITIZE command to the
analyzer to ensure new data has been collected.
When you send the :DIGitize command to the analyzer, the input to all
analyzer channels is captured and put into acquisition memory based on the
current time base and threshold settings and trigger specification. To transfer
the acquired waveform data to the controller, you must specify the
:WAVeform parameters for the waveform data prior to sending the
:WAVeform:DATA? query.
Set :TIMebase:MODE to NORMal when Using :DIGitize
:TIMebase:MODE must be set to NORMal to perform a :DIGitize or a WAVeform
subsystem query. A "Settings conflict" error message will be returned if these
commands are executed when MODE is set to DELayed. Sending the *RST
(reset) command will also set the time base mode to normal.
The number of data points comprising a waveform is either 2048 or 8192,
depending on whether the analyzer is in glitch mode. See the :ACQuire
subsystem information in the
HP 54620A/C Programmer’s Reference
online
help file for more information.
