artisan 8640B - Rear Panel Controls, and Connectors

Model 8640B TM 9-4935-601-14-7&P
REAR PANEL FEATURES
1 AUX RF OUT: nominal -5 dBm auxiliary RF
output; 500 ohm source impedance. Signal does
not contain amplitude or pulse modulation (however,
it does contain FM). On the 512-1024
MHz/Doubler Band the auxiliary RF output is one-
half the frequency of the indicated RF frequency.
2 TIME BASE Reference In/Out: input for
external, 5 MHz time base reference that is >100
mVrms; load impedance is 1 kΩ. Output for
internal, 5 MHz time base reference, level is 3 Vrms
into an open circuit; source impedance is 500 ohms.
3 TIME BASE Reference INT/EXT: switch selects
function of IN/OUT jack. INT position applies
internal reference to jack. EXT position feeds
external reference from jack to time base.
NOTE
Since the phase lock reference is the
5 MHz time base, the Model 8640B
can be phase locked to an external
reference (such as another Model
8640B) by using the TIME BASE
Reference jack and switch.
4 Line Power Module: permits operation from 100,
120, 220 or 240 Vac. The number visible in window
indicates nominal line voltage to which instrument
must be connected (see Figure 2-1). Center
conductor is safety earth ground.
WARNING
Any interruption of the protective
(grounding) conductor inside or
outside the instrument or
disconnection of the protective earth
terminal is likely to make the
instrument dangerous. Intentional
interruption is prohibited. (See
Section II).
5 Serial Number Plate: first four digits of serial
number comprise the prefix; last five digits form
sequential suffix that is unique to each instrument.
The plate also indicates any options supplied with
instruments.
