HP (Hewlett-Packard) 24A Manual De Usuario

Inputs & Outputs

Auxiliary Output

Provides an unmodulated reference signal from 2 to 26.5
at a typical minimum power level of -10

Nominal output

impedance 50 ohms. (SMA female, rear panel.)

RF Output

Nominal output impedance 50 ohms. (Precision 3.5 mm male on 20
and 26.5

models, 2.4 mm male on 40 and 50

models, front

panel.)

External ALC input

Used for negative external detector or power meter leveling. Nominal

input impedance 120

damage level

volts. See RF output

specifications. (BNC female, front panel.)

Pulse input/Output

TTL-low-level signal turns RF off. When using the standard internal
pulse generator, a TTL-level pulse sync signal preceding the RF
pulse by nominally 80 ns is output at this connector. Nominal input
impedance 50 ohms, damage level

-0.5 volts. See modulation

specifications. (BNC female, front panel:)

AM Input

Nominal input impedance 50 ohms (internally switchable to 2
damage level

volts. See modulation specifications. (BNC female,

front panel.)

FM Input

Nominal input impedance 50 ohms (internally switchable to
600 ohms), damage level

volts. See modulation specifications.

(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 mode. Damage
level

-0.5 volts. (BNC female, rear panel.)

Trigger Output

Outputs a one-microsecond-wide TTL-level pulse at 1601 points

evenly spaced across an analog sweep, or at each point in step or list
mode. (BNC female, rear panel.)
