PM Operation
This tests the operation of the PM function. After the 3152B locks to
an external trigger source, the start phase of the 3152B can be
modified in reference to the external signal using dc levels. The dc
levels are applied to the PM input and control phase shifts of 20
°
/V.
Note that this test is not applicable for the 3100M-3152B and the
3100R-3152B versions.
PM Checks
Equipment: Counter, DC supply source, function generator
Preparation:
1. Configure the function generator as follows:
Waveform: Square
Amplitude: 2
V
Output:
On
Frequency: 1
kHz
2. Using a “T” adapter, connect the function generator output to
the 3152B TRIG/PLL IN connector and the other cable to the
counter input – Channel A. Use a 50
Ω
feedthrough terminator
at the 3152B trigger input side.
3. Configure the counter as follows:
Function:
φ
A
→
B
Input:
50
Ω
, both channels
4. Connect the 3152B output to the counter input – Channel B.
5. Configure the DC source as follows:
Amplitude:
As required by the test
6. Connect the DC source to the PM input
7. Configure the model 3152B as follows:
Function Mode: Arbitrary
Waveform: Square
Wavelength: 36
points
Output: On
PLL: On
Test Procedure:
1. Modify the DC source settings and verify readings as specified
by the tests in Table 6-27.
