J1 - RF IN (Option SN)
SMA (female) 50 Ω , -20 to 0 dBm.
See Table 2.2 for other connector
options.
AC INPUT
100-240 ±10% VAC,
47-63 HZ
Uses 2 amp Slow Blo,
5mm fuse
S1 - 10MHZ SWITCH
3-position switch. INT selects internal 10MHz ref.

±3dB 10MHz signal is inserted on J2. EXT selects
external 10MHz ref from J2.
J2 - EXT 10MHZ INPUT
BNC (female) 75 Ω . Insert external 10MHz
reference here (3 dBm ± 3 dB).
J101 - RF OUT (Option SN)
Type N (female), 50 Ω .
-20 to -0 dBm.
See Table 2.2 for other
connector options.
J11 - ALARM
DB9 (female) connector.
See Table 2.1.
J8 - 10MHZ REF OUTPUT
BNC (female) 75 Ω . Outputs currently
selected 10MHz ref signal (3 dBm ±3 dB).
