Inputs & Outputs
Auxiliary Output
Provides an unmo dulated reference signal from 2 to 26.5 GHz
at a typical minimum p ower level of
0
10 dBm. Nominal output
imp edance 50 ohms. (SMA female, rear panel)
RF Output
Nominal output impedance 50 ohms. (Precision 3.5 mm male on 20
and 26.5 GHz mo dels, 2.4 mm male on 40 and 50 GHz mo dels, front
panel.)
External ALC Input
Used for negative external detector or p ower meter leveling. Nominal
input imp edance 120 k, damage level
6
15 volts. See RF output
specications. (BNC female, front panel.)
Pulse Input/Output
TTL-low-level signal turns RF o. When using the standard in
ternal
pulse generator, a TTL-level pulse sync signal preceding the RF
pulse by nominally 80 ns is output at this connector. Nominal input
imp edance 50 ohms, damage level +5.5,
0
0.5 volts. See mo dulation
specications. (BNC female, front panel.)
AM Input
Nominal input imp edance 50 ohms (internally switchable to 2 k),
damage level
6
15 volts. See mo dulation specications. (BNC female,
front panel.)
FM Input
Nominal input imp edance 50 ohms (internally switchable to
600 ohms), damage level
6
15 volts. See mo dulation specications.
(BNC female, front panel.)
Trigger Input
Activated on a TTL rising edge. Used to externally initiate an analog
sweep or to advance to the next point in step or list mo de. Damage
level +5.5,
0
0.5 volts. (BNC female, rear panel.)
Trigger Output
Outputs a one-microsecond-wide TTL-level pulse at 1601 p oints
evenly spaced across an analog sweep, or at each point in step or list
mo de. (BNC female, rear panel.)
