RF output Nominal output impedance 50 Ω.
For 20 GHz models Precision APC-3.5 male, or Type-N with Option 1ED.
For 40 GHz models Precision 2.4 mm male; plus 2.4 - 2.4 mm and
2.4 - 2.9 mm female adaptors also included.
ALC input Used for negative external detector leveling. Nominal
input impedance 120 k
Ω, damage level ±15 V.
LF output (E8257C only) Outputs the internally generated LF source.
Nominal output impedance 50
Ω.
External input 1 (E8257C only) 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 (E8257C only) 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 (E8257C only) 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 (E8257C only) Outputs a signal that follows the RF output in all pulse
modes. TTL-level compatible, nominal source
impedance 50
Ω.
Pulse sync out (E8257C only) 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
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 (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.
