HP 1660 Series

Test the 0 V User threshold
11 Move the cursor to the field to the right of Pod 1. Type 0, then press the Select key.
22 On the function generator front panel, enter +0.102 V ± 1 mV DC offset. Use the
multimeter to verify the voltage.
The activity indicators for pod 1 should show all data channels and the J-clock channel at a
logic high.

Using the Modify down arrow on the function generator, decrease offset voltage in
1-mV increments until all activity indicators for pod 1 show the channels at a logic
low. Record the function generator voltage in the performance test record.
44 Using the Modify up arrow on the function generator, increase offset voltage in
1-mV increments until all activity indicators for pod 1 show the channels at a logic
high. Record the function generator voltage in the performance test record.
