Procedure.
1. Align the 0 mV level of the signal with the center graticule on the oscillo-
scope.
2. Change the oscilloscope vertical offset to 700mV.
3. Confirm the signal level is 700 mV" 7 mV.
4. Change the oscilloscope waveform to CH1 off, waveform to CH2, and
vertical offset to –350 mV.
5. Align the –350 mV level of the signal with the center graticule on the
oscilloscope.
6. Change the oscilloscope vertical offset to 350 mV.
7. Confirm the signal level is 350 mV" 7 mV.
8. Press the TIMING SIGNALS button on the TSG1001 front panel to set the
TIMING SIGNALS to BOWTIE.
