Signal Generator Overview

Rear Panel Overview

21. TRIG IN Connector

This female BNC connector accepts a TTL or CMOS signal for triggering operations, such as

point-to-point in manual sweep mode or an LF sweep in external sweep mode. Triggering can

occur on either the positive or negative edge. The damage level is

≥ +10 V or ≤−4V.

22. 10 MHz IN Connector

This female BNC connector accepts a −3.5 to +20 dBm signal from an external timebase

reference that is within

±10 ppm (standard timebase) or ±1 ppm (high stability timebase). The

nominal input impedance is 50

Ω. The signal generator detects when a valid reference signal is

present at this connector and automatically switches from internal to external reference

operation.

23. SWEEP OUT Connector

This female BNC connector provides a voltage range of 0 to +10 V. When the signal generator

is sweeping, the SWEEP OUT signal ranges from 0 V at the beginning of the sweep to +10 V

at the end of the sweep regardless of the sweep width. In CW mode this connector has no

output. The output impedance is less than 1

Ω and can drive 2 kΩ.

24. 10 MHz OUT Connector

This female BNC connector provides a nominal signal level of +3.9 dBm ±2 dB, and an output

impedance of 50

Ω. The accuracy is determined by the timebase used.

25. BASEBAND GEN REF IN Connector

With Option 001 and 002 installed, the BASEBAND GEN REF IN connector accepts a 0 to

+20 dBm sine wave or TTL square wave signal from an external timebase reference. This

digital modulation reference clock is used by the internal baseband generator for both

component and receiver test applications (only the internal baseband generator can be locked

to this external reference; the RF frequency remains locked to the 10 MHz reference). The

nominal input impedance is 50

Ω at 13 MHz, AC-coupled.

With Option 001 or 002 installed, this connector accepts a TTL or >

−10 dBm sine wave

external reference at rates from 250 kHz through 100 MHz. The internal clock for the

arbitrary waveform generator is locked to this signal when external reference is selected in

the ARB setup. The minimum pulse width must be > 10 ns. The damage levels are > +8 V and

−8 V.

This female BNC connector is provided only on signal generators with Options 001 and 002.

On signal generators with Option 1EM, this output is changed from a BNC to an SMB
