Vertical Check
The following checks verify the vertical accuracy of your oscilloscope.
To check DC gain accuracy, perform the following steps.
1. Use the 50 Ω precision coaxial cable to connect the standard amplitude
output of the DC calibration generator to the TAS 200 series oscilloscope
CH 1 (CH 2) input. See Figure 2 below.

2. Set up the oscilloscope as follows:
VERTICAL MODE CH1 (CH2)
CH 1 (CH 2) AC-DC DC
CH 1 (CH 2) VOLTS/DIV 1 mV
TRIGGER M ODE AUTO
HORIZONTAL SEC/DIV 0.5 ms
CH 1 (CH 2) GND Out (release)
3. Set the oscilloscope CH 1 VOLTS/DIV S cale and calibration generator
output to each of the values listed in Table 13; then verify that the readings
on the oscilloscope remain within the limits of the Displayed Signal
