Key to Crystal type: AT F/OT = AT cut, fundamental or overtone
AT OT = AT cut, overtone, 3rd or 5^th Key to tuning: E/M = electrical and mechanical
SC OT = SC cut overtone, usually 3^rdE = electrical only
AT OT/M = AT cut, overtone + internal multiplication M = mechanical only
Connectors: SMA/B/C RF output available on all models * Fast warm up version
MCX & BNC RF output available on 100/200 series # Mounting plate measures 61 x 40mm
D9 std. on 100/200 series for power + electrical tuning control
Solder terminals std. on 600 series for power (+ electrical tuning control if specified)
NOTE: HCD125, 126, 145 Models now obsolete and only made to special order, please contact factory.
