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 1us pulses (nominal) across a ramp sweep.

When using LF Out, provides 2 us pulse at start of LF sweep.

Trigger input Accepts TTL 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 (nominal) level during

retrace and bandswitch intervals. Supplies – 5V (nominal)

level when the RF frequency is at a marker frequency.

EFC > 0.25 ppm for –5 to +5 V. Input impedance: >1 M Ω
