30 P5205 Instruction Manual
NOTE. These procedures assumethat you are using an oscilloscope
that automaticallydisplays the correct volts/divisionscale factor for
the attenuationsetting of the probe. If not, you musttake the
attenuationsetting of the probe into account when setting the
volts/divisionon the oscilloscope.
Differential Gain Accuracy
1. Set the volts/divisionon channel 2 of the oscilloscope to 2 V.
HTrigger on channel 2.
HSelect 1 MΩimpedance (ifoption exists on oscilloscope).
HConnect coaxial cable between TRIG OUT of the generator
(rear of Wavetek 9100) and channel 2 of the oscilloscope.
2. Set the volts/divisionon 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 coaxialcable from SIG OUT of the generator (rear
of Wavetek 9100) to channel 1 of the oscilloscope.
5. Set the generat or to 0.1 V and 1 kHz (AUX, square wave , 1 MΩ
load). Enable the output.
6. Select the amplitudemeasurement 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 cabl e from
channel 1 ofthe oscilloscope and SIG OUT of thegenerator.
8. Connect the outputof the probe to channel 1 of the oscilloscope.
9. Attach the ModifiedBNC adapter to the SIG OUT of the
generator.
