External input 2 Drives either AM, FM, or ΦM. 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.

Data clock input Accepts a data clock signal to synchronize serial data for use

with internal baseband generator (Option 602). Maximum

rate 50 MHz. Damage levels are > + 5.5 and < –0.5 V.

Data input Accepts serial data for use with internal baseband generator

(Option 602). Maximum rate 50 Mb/s. Data must be valid

on the falling edges of data clock (normal mode) or the

symbol sync (symbol mode). Damage levels are > + 5.5

and < –0.5 V.

I input Accepts an "I" input either for I/Q modulation or for

wideband AM. Nominal input impedance 50 or 600 Ω.

Damage levels are 1 V

rms

and 5 V

peak

Q input Accepts a "Q" input for 1/0 modulation. Nominal input

impedance 50 or 600 Ω. Damage levels are 1 V

rms

and

5 V

peak

Symbol sync input Accepts symbol sync signal for use with internal baseband

generator (Option 602). Symbol sync might occur once

per symbol or be a single, one bit wide pulse to synchronize

the first bit of the first symbol. Maximum rate 50 MHz.

Damage levels are > +5.5 and < –0.5 V.

Auxillary interface (Dual mode) Used for RS-232 serial communication and for Master/Slave

source synchronization. (9-pin D-subminiature female

connector) For Master/Slave operation use Agilent

Technologies part #8120-8806 Master/Slave interface cable.

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

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 +4 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 (nominal) at the end of sweep,

regardless of sweep width.

When connected to an Agilent 8757D scalar network

analyzer (Option 007), generates a selectable number of

equally spaced 1 us pulses (nominal) 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, can drive 2000 Ω.

Rear panel connectors

(All connectors are BNC female

unless otherwise noted.)

1. Digital inputs and output are 3.3 V CMOS unless indicated otherwise. Inputs will accept 5 V CMOS, 3V CMOS,

or TTL voltage levels.
