Equipment: Counter, function generator
Preparation:
1. Configure the function generator as follows:
Waveform: Square
Amplitude: 2
V
Output:
On
Frequency:
As required by the tests
2. Connect the function generator output to the 3152B TRIG/PLL
IN connector. Using a “T” connector, connect the same output
to the counter input – Channel A. Use a 50
Ω
feedthrough
terminator at the 3152B trigger input side
3. Configure the counter as follows:

4. Connect the 3152B output to the counter input – Channel B
5. Configure the model 3152B as follows:
Function Mode: Arbitrary
Wavelength: 1000
points
Output: On
PLL: On
Phase Offset: As required by the test
Test Procedure:
1. Verify counter phase readings as specified in Table 6-26.
