5. Store and then recall the waveform.
6. Use the oscilloscope cursors to display the
D
voltage of the
recalled waveform. Measure the low-frequency portion of the
waveform near the back corner. See figure 4–3 below.

7. Record the
D
voltage as V
1
.
8. Disconnect the coaxial cable from the oscilloscope calibrator
output and reconnect it to the channel 1 output of the 1103 probe
power supply. Remove the SMA-to-BNC adapter from the
oscilloscope calibrator output.
9. Connect the P6205 probe output to the 1103 power supply
channel 1 input. The P6205 does not use the offset capability of
the 1103 power supply; the offset control setting is not important.
10. Mate the GR connector ends of the 50
W
termination adapter and
the male SMA-to-GR adapter. Connect the mated assembly to the
oscilloscope calibrator output. Insert the probe tip firmly into the
50
W
termination adapter. See Figure 4–4 below.
