SECTION 1
Perhrmance Verification
1.6.4
Frequency Response (Triangle,
Sawtooth, Square)
1. Connect the function spthesizer to
a
timer/counter
as shown in Figure l-1. Turn on both instruments.
2. Restore factory defaults on the Model 3930A by
pressing SHJFT PRST.
3. Program a 1kHz triangle wave of 3OVp-p.
4. Set the timer/counter
to display the peak-to-peak
voltage at Channel A, and verify that the voltage
reading is within the limits specified in Table l-5.
Call this reading REF.
5. Change the frequency to 5kHz. The new reading
should be between 0.97 times the REF reading and
1.03 times the REF reading.
6. Modify the frequency and function settings of the
synthesizer according to Table 1-5, and verify that
the corresponding readings are within the specified
limits.
