Auxiliary interface Used for RS-232 serial communication and for master/slave
(Dual mode) source synchronization. (9-pin D-subminiature female
connector) For master/slave operation, use Agilent part
number 8120-8806 master/slave interface cable.
GPIB Allows communication with compatible devices
LAN Allows 10baseT LAN communication
10 MHz input Accepts a 10 MHz external reference (timebase) input.
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 from 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 µs pulses (nom) across a ramp (analog) sweep.
Number of pulses can be set from 101 to 1601 by remote
control from the 8757D.
Output impedance: < 1 Ω (nom), can drive 2000 Ω.
Stop sweep In/Out Open-collector, TTL-compatible input/output. In ramp sweep
operation, provides low level (nominally 0 V) during sweep
retrace and bandcross intervals, and high level during the
forward portion of the sweep. Sweep will stop when grounded
externally; sweep will resume when allowed to go high.
Trigger output (dual mode) Outputs a TTL signal. High at start of dwell, or when waiting
for point trigger; low when dwell is over or point trigger is
received. In ramp sweep mode, provides 1601 equally-spaced
1 µs pulses (nom) across a ramp sweep. When using LF out,
provides 2 µs pulse at start of LF sweep.
Trigger input Accepts 3.3 V CMOS signal for triggering point-to-point in
manual sweep mode, or to trigger start of LF sweep.
Damage levels ≥ +10 V or ≤ –4 V.
Source module interface Provides bias, flatness correction, and leveling connections
to the Agilent model 83550 Series mm-wave source modules.
Source settled Provides an output trigger that indicates when the signal
generator has settled to a new frequency or power level.
High indicates source not settled, low indicates source settled.
Z-axis Blank/Markers During ramp sweep, supplies + 5 V (nom) level during
retrace and bandswitch intervals. Supplies – 5 V (nom)
level when the RF frequency is at a marker frequency.
10 MHz EFC (Option UNX only) Accepts an external DC voltage,
ranging from –5V to +5V, for electronic frequency control (EFC)
of the internal 10 MHz reference oscillator. This voltage
inversely tunes the oscillator about its center frequency
approximately –0.07 ppm/V. The nominal input impedance
is greater than 1 MΩ
.25 – 3.2 GHz coherent Outputs RF signal modulated with FM or ΦM but not I/Q,
carrier output AM or pulse. Nominal power 0 dBm. Frequency range from
250 MHz to 3.2 GHz. Not useful for output frequency > 3.2 GHz.
Damage levels 20 V
