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 – 5 V (nominal)
level when the RF frequency is at a marker frequency.
10 MHz EFC (Option UNR only) Accepts an external DC voltage, ranging
from –5 V to +5 V, 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 M.
