When measuring the pulse width or phase difference of a single pulse, you can select
the level of the data signal at which to make the measurement (activate the trigger).
Slice level refers to the signal level used to binarize the RF signal, and this slice level is
used to activate the trigger.
Trigger Mode and Slice Level
• AUTO (auto mode)
The RF signal is binarized using the slice level that is detected by the auto slice
circuit. For information about the auto slice function, see section 2.4.
• MAN (manual mode)
The slice level can be set in the range below when the trigger mode is set to Manual.
The RF signal is binarized using the specified slice level.
• When the measurement function is set to PW (pulse width), AGC is OFF (see
section 4.9), and the equalizer is OFF:
Setting range: –2.000 to 2.000 V (in steps of 1 mV)
• Other than the above:
Setting range: –1000 to 1000 (in steps of 1)
