Arming and Gating Checks
(8-1) Connect CAL2 to the ARM1 input channel. Connect CAL1 to the delay line and the
delay line to the CH1 input channel.
(8-2) At Menu #7, select PERIOD, CH1, TRIG = 50%-50%. Select AUTO ARM and
CONTINUOUS mode on the front panel, and press FUNC. Verify the displayed
measurement is 5000 psec ±10 psec with JITTER <6 psec.
(8-3) Set the function generator to output a square wave with a 5 nsec wide duty cycle, and a
1V
pk-pk
(8-4) Select EXTERNAL ARMING on ARM2 mode. Verify sample size = 10,000.
(8-5) Connect the CAL1 to the CH1 input channel and CAL2 to the CH2 input channel.
Connect the output of the function generator to the ARM2 input. Go to Menu #9 and set
GATE = "ON H". Then press CONTINUOUS.
(8-6) Determine the approximate amount of time it takes the DTS to obtain l0,000 samples.
This can be done by watching Menu #6. Then change the gating duty cycle on the
function generator from 5 nsec to 2 nsec. The time to obtain the 10,000 samples should
now be more than twice as long.
(8-7) Remove all test equipment and cabling from the DTS.
