Clock Slope

Sets the edge of the clock at which the instrument checks the signal states: at the ris-

ing edge, the falling adge, or at both edges.

Remote command:

TRIGger:STATe:CSOurce:EDGE on page 177

Set Pattern

Defines the pattern: the states of the input channels and their logical combination. If

R&S RTH-B1 is installed, active digital channels are also included in the pattern defini-

tion.

For details, see Chapter 2.5.6, "Pattern Trigger (R&S RTH-K19)", on page 57.

Remote command:

TRIGger:STATe:CHANnel<1..22> on page 176

2.5.8 Runt Trigger (R&S RTH-K19)

A runt is a pulse lower than normal in amplitude. The amplitude crosses the first level

twice in succession without crossing the second one. In addition to the upper and lower

levels, you can define a time limit for the runt in the same way as for width triggers. For

example, the runt trigger can detect signal parts remaining below a specified threshold

amplitude because I/O ports are in undefined state.
