PERFORMANCE TEST
Test set up:
Settings/procedure:
1
-
Apply a 200 MHz (PM3390B/94B), 100 MHz (PM3380B/84B) or 60 MHz
(PM3370B) sine-wave signal of 0.8 V(pp into 50
Ω
) to input CH1.
2
-
Press the AUTOSET key.
3
-
Use a 50
Ω
termination. Use the internal termination when available.
4
-
Switch all channels ON. PM3370B/80B/90B: switch CH2 on.
5
-
Set all channels to 0.1 V/div.
6
-
Adjust the generator to a signal amplitude of 8 div.
7
-
Activate the GND function of CH2, CH3, and CH4. PM3370B/80B/90B:
activate GND of CH2.
Requirements:
-
Verify that the displayed amplitude the channels with no input signal applied
is less than 0.16 divisions, (better than 50:1).
Repeat the above settings and procedure for PM3384B/94B:
-
Input signal applied to CH2. CH1, CH3, and CH4 input GND.
-
Input signal applied to CH3. CH1, CH2, and CH4 input GND.
-
Input signal applied to CH4. CH1, CH2, and CH3 input GND.
Repeat the above settings and procedures for PM3370B/80B/90B:
-
Input signal applied to CH2. CH1 input GND.
For all models:
-
Press the ANALOG key (’DIGITAL MODE’ is displayed briefly) and repeat the
tests in this chapter for the digital mode.
-
Press the ANALOG key (’ANALOG MODE’ is displayed briefly) to return to
analog mode.
