ALC input

Used for negative external detector leveling. Nominal

input impedance 120 kΩ, damage level ±15 V.

LF output

Outputs the internally generated LF source. Nominal

output impedance 50 Ω.

External input 1

Drives either AM, FM, or

FM. Nominal input impedance

50 or 600 Ω, damage levels are 5 V

rms

and 10 V

peak

.

External input 2

Drives either AM, FM, or

FM. Nominal input impedance

50 or 600 Ω, damage levels are 5 V

rms

and 10 V

peak

.

Pulse/trigger gate input

Accepts input signal for external fast pulse modulation.

Also accepts external trigger pulse input for internal

pulse modulation. Nominal impedance 50 Ω. Damage

levels are 5 V

rms

and 10 V

peak

.

Pulse video out

Outputs a signal that follows the RF output in all pulse

modes. TTL-level compatible, nominal source

impedance 50 Ω.

Pulse sync out

Outputs a synchronizing pulse, nominally 50 ns width,

during internal and triggered pulse modulation.

TTL-level compatible, nominal source impedance 50 Ω.

Auxiliary interface (dual mode) Used for RS-232 serial communication and for

master/slave source synchronization.

(9-pin subminiature female connector).

GPIB

Allows communication with compatible devices

LAN

Allows 10BaseT LAN communication

10 MHz input

Accepts an external reference (timebase) input (at 1,

2, 2.5, 5, 10 MHz for standard and 10 MHz only for

Option UNX and UNR)

Nominal input impedance 50 Ω

Damage levels > +10 dBm

10 MHz output

Outputs internal or external reference signal. Nominal

output impedance 50 Ω. Nominal output power +8 dBm.

Sweep output (dual mode)

Supplies a voltage proportional to the RF power or

frequency sweep ranging form 0 volts at the start of

sweep to +10 volts (nom) at the end of sweep,

regardless of sweep width.

During CW operation, supplies a voltage proportional

to the output frequency, +10 volts (nom) corresponding

to the maximum specified frequency.

When connected to an Agilent 8757D scalar network

analyzer (Option 007), generates a selectable number

of equally spaced 1 us pulses (nom) across a ramp

(analog) sweep. Number of pulses can be set form

101 to 1601 by remote control from the 8757D.

Output impedance: < 1 Ω (nom), can drive 2000 Ω.
