P5205 Instructi on Manual

NOTE. These procedures assume that you are using an oscilloscope

that automatically displays the correct volts/division scale factor for

the attenuation setting of the probe. If not, you must take the

attenuation setting of the probe into account whe n setting the

volts/division on the oscilloscope.

Differential Gain Accuracy

1. Set the volts/division on channel 2 of the oscilloscope to 2 V.

H Trigger on channe l 2.

H Select 1 MΩ impedance (if option exists on oscilloscope).

H Connect coaxial cable between TRIG OUT of the generator

(rear of Wavetek 9100) and channel 2 of th e oscilloscope.

2. Set the volts/division on channel 1 of the oscilloscope to

50 mV/div.

3. Set the seconds/div to 200 s, and the acquisition mode to

average 32.

4. Connect the coaxial cable from SIG OUT of the generator (rear

of Wavet ek 9100) to channel 1 of the oscilloscope.

5. Set the generator to 0.1 V and 1 kHz (AUX, square wave, 1 MΩ

load). Enable the output.

6. Select the amplitude measurement on the oscilloscope and record

the DC amplitude (∼ 100 mV) of square wave. This measurement

is only the oscilloscope.

7. Disable the generator output. Disconnect the coaxial cable from

channel 1 of the oscilloscope and SIG OUT of the generator.

8. Connect the output of the probe to channel 1 of the oscilloscope.

9. Attach the Modified BNC adapter to the SIG OUT of the

generator.
