Check Delta Time
Measurement Accuracy
80
This test checks the Delta-time measurement accuracy (DTA) for a given
instrument setting and input signal.
Connect a 50 Ω coaxial cable from the signal source to the oscilloscope channel 1,
as shown in the following illustration.
WARNING.
The generator is capable of providing dangerous voltages. Be sure to
set the generator to off or 0 volts before connecting, disconnecting, and/or moving
the test hookup during the performance of this procedure.
