The 105B quartz frequency standard provides excellent long term/short term stability characteristics, spectrally pure output, and excellent reliability. The crystal, oscillator, and AGC circuit are enclosed in a proportional oven for reduced temperature effects. It also has a built-in 6 hour standby battery for uninterrupted operation.

Outputs: 5 MHz, 1 MHz, 100 kHz; 1 Vrms into 50 ohms

Clock output: 1 MHz, 0.5 Vrms into 1 kohm rear connector

Frequency stability: <5 x 10 to the -10th per day

Distortion (harmonic): >40 dB

Distortion (nonharmonic): >80 dB

Frequency adjustment (fine): ą5 x 10 to the - 8th range with digital dial reading parts in 10 to the 10th

Frequency adjustment (coarse): ą1 x 10 to the - 6th range front panel screwdriver control

Standby supply capacity: 6 hours at 25° C

Connectors: BNC(f)
