This clears the Time Tagging event registers of any data prior to the
next step.
4 On the computer or terminal, type :FORMAT:DATA ASCII and press the
Return key.
This sets the output format of the Time Tagging Data to an ASCII
string for easier interpretation.
5 Refer to Chapter 2, “Features and Functions,” in the 58503B/59951A
Getting Started Guide to identify types of stimulus equipment that
could be used for this test.
A suggested general-purpose device could be a pulse generator, set to
output a TTL level pulse.
6 Use this signal to send an event to each of the three Time Tagging
inputs.
7 From the terminal or computer, send the following query commands to
verify that an event was recorded in each of the Time Tagging event
registers. Note that there is a space between the question mark (?) and
the quotation mark (“) in the following commands.
:SENSE:DATA? “TSTAMP 1”
:SENSE:DATA? “TSTAMP 2”
:SENSE:DATA? “TSTAMP 3”
Note that the actual date and time of the record is not being tested.
8 Verify that each response is the following format:
yyyy,mm,dd,hh,mm,ssssssss,xxxxxxxxxx
9 On the terminal, type :SENSE:DATA:CLEAR and press the Return key.
10 This again clears the Time Tagging event registers of any data from
this test.
11 Mark Pass or Fail in Line 6 on the Operational Verification portion of
the 59551A Performance Test Record, located at the end of this
chapter.
