Agilent Technologies 1670G ECL

Query :CHANnel<N>:COUPling?

The COUPling query returns the current input impedance for the specified

channel.

Returned Format [:CHANnel<N>:COU Pl ing:] {DC|AC|DCFifty }<NL>

Example OUTPUT XXX;":CHANNE L1:COUPLING?"

ECL

Command :CHANnel<N>:EC L

The ECL command sets the vertical range, offset, and trigger levels for the

selected input channel for optimum viewing of ECL signals. ECL values are:

Range: 2.0 V (500 mV per division)

Offset: -1.3 V

Trigger level: -1.3 V

<N> {1|2}

Example OUTPUT XXX;":CHANNE L1:ECL"

To return to "Preset User", change the CHANnel:RANGe, CHANnel:OFFSet, or

TRIGger:LEVel value.
