Performance Verification
Trigger Level Accuracy Check
a Turn on only channel 2 and set to 100 mV/div with 200 mV offset.
b Set the timebase to 10 ns/div with 24 ns Delay.
c Set the trigger source to the front panel.
6 Set the input to be 1 V p-p.
a Turn on the Vmax function.
b Use a binary search to adjust the power level of the 83712B until Vmax = 500 mV ± 2 mV.
c Set the channel 2 offset to 0.
7 Set the DUT to negative slope trigger.
8 Using the Tvolt command query the time of the 0 ps location for the first falling edge.
9 Repeat the following for each data point.
a Adjust the trigger level to the data point.
b Set the channel 2 offset to the same as the trigger level.
c Use the Vtime command to read the voltage level. Use the time acquired from
10 Set the DUT to positive slope trigger.
11 Using the Tvolt command query the time of the 0 mV location for the first rising edge.
12 Repeat the following for each data point.
a Adjust the trigger level to the data point.
b Set the channel 2 offset to the same as the trigger level.
c Use the Vtime command to read the voltage level. Use the time acquired from
13 Compare each data point to the specs for both the positive and negative slope triggers
