Signal Generator Overview

Rear Panel

27. TRIGGER OUT

This female BNC connector, in step/list sweep mode, outputs a TTL signal that is high at the start of a dwell sequence or when waiting for a point trigger in manual sweep mode. The signal is low when the dwell is over or when a point trigger is received. In ramp sweep mode, the output provides 1601 equally spaced 1 μs pulses (nominal) across a ramp sweep. When using LF Out, the output provides a 2 μs pulse at the start of an LF sweep. The nominal impedance for this connector is less than 10 ohms.

28. TRIGGER IN

This female BNC connector accepts a 3.3V CMOS signal, which is used for point- to- point triggering in manual sweep mode, or in a low frequency (LF output) or analog (AM, FM, and ΦM) external sweep trigger setup. Triggering can occur on either the positive or negative edge of the signal start. The damage level is ≤ −4 V or ≥ +10 V. The nominal input impedance for this connector is approximately 4.2 kohms.

29. SOURCE SETTLED

This female BNC connector provides a 3- volt CMOS output trigger, indicating when the signal generator has settled to a new frequency or power level. A high indicates that the source has not settled. A low indicates that the source has settled. The nominal output impedance for this connector is less than 10 ohms.

30. SOURCE MODULE INTERFACE

This interface is used to connect to compatible Agilent Technologies 83550 Series mm- wave source modules.

31. RF OUT

This connector outputs RF and microwave signals. The nominal output impedance is 50 ohms. The reverse power damage levels are 0 Vdc, 0.5 watts nominal. On signal generators without Option 1EM, this connector is located on the front panel. The connector type varies according to frequency option.

32. EXT 1

This female BNC input connector (functional only with Options UNT, UNU, or UNW) accepts a ±1 Vp signal for AM, FM, and ΦM. For these modulations, ±1 Vp produces the indicated deviation or depth. When ac- coupled inputs are selected for AM, FM, or ΦM and the peak input voltage differs from 1 Vp by more than 3 percent, the HI/LO display annunciators light. The input impedance is selectable as either 50 or 600 ohms; the damage levels are 5 Vrms and 10 Vp. On signal generators without Option 1EM, this connector is located on the front panel.
