Programmable Pulse Verification (59551A Only)
1 Enter the following commands from the terminal or computer:
:PULSE:CONTINUOUS:PERIOD 1
This sets the period to 1 second.
:PULSE:CONTINUOUS:STATE ON
This sets the programmable pulse output to provide a continuous
stream of pulses.
:PULSE:START:DATE <four-digit year>, <month>, <day>
2 Set the year, month, and day to the same values read in step 2 in the
previous procedure “Time Tagging Verification.”
Example:
:PULSE:START:DATE 1995, 7, 25 is July 25, 1995.
:PULSE:START:TIME <hours>, <minutes>, <seconds>
3 Set the hours, minutes, and seconds to the same values observed in
step 2 of the previous procedure “Time Tagging Verification.”
Example:
:PULSE:START:TIME 13, 1, 5 is 13:01:05 in 24-hour format.
NOTE Setting the time to a value earlier than the present time will start the
pulse stream immediately. If a time is input with a value some time in
the future, the pulse stream will not start until that time is attained.
4 Set the oscilloscope sweep rate to 5 msec/div, input amplitude to
5 Volts/div, and input coupling to dc.
5 Connect the oscilloscope to the rear-panel Programmable Pulse output
as shown in Figure 5.
