b. Connect the oscilloscope to test point A4TP203 using an ac coupled 10 to 1 probe.
c. Adjust A4C109,. using a non-conductive tool, until the error voltage is reduced to its
minimum peak to peak amplitude with no discontinuities.
5-33. 124/135/150/600 ohm Output Level Accuracy Adjustment.
- 5-34, These adjustments set the absolute amplitude accuracy of the balanced outputs.
NOTE
Perform the 75 ohm Output Level Adjustment before adjusting
these output levels.
Required Equipment:
ac voltmeter
-hp- Model 3455A with Option 001
or -hp- Model 3490A
termination resistors
124 ohm, 3336B only
-hp- Part No. 0698-6284
135 ohm, 3336B only
-hp- Part No. 0698-5197
150 ohm, 3336A only
-hp- Part No. 0757-0715
600 ohm, 3336A and 3336B
-hp- Part No. 0698-5405
NOTE
The 3336 must be ON for 30 minutes before attempting this ad-
justment.
a. Terminate a balanced output with the corresponding termination resistor.
b. Connect the ac voltmeter to the terminated output.
c. Activate the output and use the following table to determine:
—the -hp- 3336 amplitude setting
—the -hp- 3336 frequency setting
—the component to adjust
—the ac output voltage to adjust to
—the ac output voltage tolerance
