SDS5000XSeries Digital Oscilloscope Service Manual
43/ 90
EXT/5
435mV
Abs(Error) < 103.5mV
Steps:
1.
Connect channel 1 and external trigger channel of the oscilloscope to
the 9500B with a BNC T connector, as shown in
2.
Set the oscilloscope Sec/Div to 500 us/div.
3.
Set the oscilloscope Volts/Div to 150mV/div, trigger source to EXT,
trigger slope to positive and coupling mode to DC.
4.
Set the
impedance of the 9500B to 1 MΩ, frequency to 1 kHz,
amplitude to 4*Volts/Div, and waveform to sine.
5.
Set the trigger level to 450mV.
6.
Press the Measurebutton on the front panel of the oscilloscope to
display Level@xmeasurement.
7.
Record the value of Level@x, calculate the level error(error = 300mV -
Level@x).
8.
Check if the trigger level error is in the limited range above.
9.
Set the trigger level to 0 mV and -450mV,repeat step 5 to step 8.
10.
Set trigger slope to negative, repeat step 5 to step 9.
11.
Set the oscilloscope Volts/Div to 345mV/div, trigger source to EX/5,
trigger slope to positive,and coupling mode to DC.
12.
Set the
impedance of the 9500B to 1 MΩ, frequency to 1 kHz,
amplitude to 4*Volts/Div, and waveform to sine.
13.
Set the trigger level to 1035mV.
14.
Record the value of Level@x, calculate the level error(error = 300mV -
