3-position switch. INT selects internal 10MHz ref.
AUTO selects internal 10MHz ref, unless a 3dBm
±3dB 10MHz signal is inserted on J2.
EXT selects external 10MHz ref from J2. J101 - RF INPUT
SMA (female) 50
11.7 to 12.2 GHz
-35 dBm max input signal
See Table 2.2 for other
connector options.
J8 - 10MHZ REF OUTPUT
BNC (female) 75
. Outputs currently
selected 10MHz ref signal (3 dBm ±3 dB).
J1 - L-BAND OUTPUT
BNC (female) 50
. 0.95 to 2.00 GHz,
0 dBm max input signal. See Table 2.2
for other connector options.
J2 - EXT 10MHZ INPUT
BNC (female) 75
. Insert external
10MHz reference here (3 dBm ± 3 dB).
J11 - ALARM
DB9 (female) connector.
