To test the oscillator output
These tests are optional. The oscillator outputs are not specified in the instrument
performance specifications. The values given are typical. Results are not recorded in the
Performance Test Record.
Equipment Required
Equipment requirement is not critical and choices are at the discretion of the user. A high
quality oscilloscope should be sufficient.
Procedure
Press Recall ,thenpress cir toset the oscilloscope to default conditions.
Use a BNC cable to connect the rear panel AC cal output to the channel 1 input of
the oscilloscope under test and press autoscale .
Make automatic amplitude and frequency measurements of the signal.
Press (blue ) V amptd 1 forthe amplitude
andpress (blue) Frequency 1 for the frequency.
The signal into 1 MQ should be an approximately 800 mVp-p square wave at
approximately 500 Hz. Into 50 Q the amplitude is approximately 400 mVp-p.
Disconnect the AC cal output from the channel 1 input and connect it to another
oscilloscope.
Press Utility , thenpress service menutotumoncal select 0
(0. 10 MHz timebase to AC BNC).
The signal will be approximately 10 MHz and 800 mVp» into 1 MQ.
