Trigger level settings

The trigger level may be set to a unique value for each active step. Use the TLEVx command
to set appropriate trigger levels for each active step in the waveform. Make sure that the maxi-
mum setting for the selected trigger level range is not exceeded.
page 3-29.)
Figure 3-7 has 5 rising edge steps and 4 falling edge steps. Set the trigger levels for each step
measurement according to the expected pulses. Based on the wave form, the nine trigger levels
could be set as follows:
Rising:
TLEV1
TLEV2
TLEV3
TLEV4
TLEV5
