This calibration consists of six steps from Step 0 to Step 5, but in this manual,
perform only Step 4 (Magic Cal.-2). Other calibration constants are restored by
using the data acquired by ATS at the factory or during servicing.
Basic steps are to observe output waveforms on the oscilloscope screen, and to
determine the range of abnormal outputs, which appears on the oscilloscope as a
broken waveform, by adjusting the delay in the TEK0015 Data Output.
1. Install the test hookup and preset the instrument controls:
a. Hook up the oscilloscope:
„
Attach the SMA terminations to the Channel 1 Analog (–) and Channel 2
Analog (–) Outputs on the front panel of the arbitrary waveform generator.
„
Attach the SMA-BNC adapters to the CH 1 and CH 2 Input connectors of
the oscilloscope.
„
Connect the SMA cables from the Channel 1 Analog (+) and Channel 2
Analog (+) Outputs on the front panel of the arbitrary waveform generator
to the CH 1 and CH 2 Inputs of the oscilloscope, as shown in Figure 3-4.
