This rear panel female BNC connector accepts a -5 to + 10
dBm
signal from an external time base reference which is
within
510
ppm of 10 MHz or any sub-multiple down to 1
MHz. The nominal input impedance is 50
61.
This connector
detects when a valid reference signal is connected to it and
automatically switches from internal to external reference
operation.
This rear panel female BNC connector provides a nominal
signal level of 0
dBm,
and output impedance of 50
0.
The
accuracy is determined by the tune base used.
This front panel female BNC connector is used for external
power meter leveling or external negative detector leveling.
The damage level is
f15
V.
The nominal input impedance is
100
kQ.
This rear panel female BNC connector accepts the amplitude
modulating signal input when External AM is enabled. The
nominal input impedance is 3.5
kQ.
The damage level is
f15
v.
This rear panel female BNC connector accepts the frequency
modulating signal input when DC or AC FM is enabled. The
nominal input impedance is 1
k62.
The damage level is
f15
v.
This rear panel female BNC connector can be used as
either an external pulse input or output for internal pulse
modulation. In either case, it is TTL level compatible and
has a nominal impedance of 5
khl.
The damage level is
2
+lOVor<
-5V.
A TTL high level (>
+2
V)
enables the selected power level
to be at the RF OUTPUT connector, while a TTL low level
turns the RF off.
