3. Tune Spectrum Analyser for minimum display ampli-
tude and adjust gain so that fundamental corresponds to
0dB.
4. Change 8020 frequency setting to 10 MHz.
5. Verify that all harmonics are less than -25dB
6. Change 8020 frequency setting to 20 MHz.
7. Verify that all harmonics are less than -25dB.
5-10-7. Sine Flatness
Level flatness: .5 dB to 2.000 MHz; .5 dB to 20.00 MHz
Equipment: Oscilloscope
1. Set 8020 as follows:
CONTROL POSITION
Frequency 2.000 KHz
Amplitude 15.0 V
Offset 0.00 V
Trigger Mode Continuous
Display Modify FREQ
Operating Mode Normal
Output Sine
2. Connect 8020 OUTPUT to oscilloscope and set
oscilloscope to display waveform within exactly 6
vertical divisions.
3. Change 8020 Frequency setting to 2.000 MHz. Verify
that peak to peak of displayed waveform is greater than 5.7
divisions.
4. Change 8020 Frequency setting to 20.00 MHz. Verify
that peak to peak of displayed waveform is greater than 5.1
divisions.
5-10-8. Trigger, Gate, Manual
Specifications: Each trigger input cycle or manual button
press generates a gated output signal or a single output
cycle
Equipment: 8200 Function Generator, Oscilloscope
1. Set 8020 as follows:
CONTROL POSITION
Frequency 20.00 KHz
Amplitude 15.0 V
Offset 0.00 V
Trigger Mode Gated
Display Modify FREQ
Operating Mode Nornal
Output Sine
2. Set external 8200 function generator to 1 KHz and 4 V
positive pulse. Connect external 8200 function generator
to TRIG IN BNC. Check on oscilloscope for 8020 output
signal.
3. Disconnect external function generator and press the
MANUAL push- button. Check on oscilloscope for signal
present at 8020 output as long as MANUAL button is
depressed.
4. Change 8020 setting to Triggered mode.
5. Reconnet external function generator to 8020 TRIG IN
terminal.
6. Check on oscilloscope for 8020 output signal. A single
waveshape is generated on every rising edge of the trigger-
ing signal.
7. Change 8020 setting to 10Hz.
8. Disconnect external function generator and press the
MANUAL button. check on oscilloscope for a single pulse
after each time the MANUAL button was depressed. Use
TTL output of external function generator to trigger oscil-
loscope externaly whenever necessary.
