 HP 0105-6100 assembly schematic

 used for 10811-60109 OCXO installation in HP 5061A, 5065A, 105B, and other instruments

The HP 105B is an economical, precision frequency standard with performance comparable to the best of the expensive primary standards. It is ideal for use in mobile and fixed installations, including applications in navigation and advanced communications. The 5-MHz output of the HP 105B has excellent short-term stability and spectral purity with a signal-to-noise ratio of better than 90 dB.

The HP 105B is based on the HP 10811D(10811-60109), an oven-controlled crystal oscillator with exceptional reliability. Its low aging rate and fast warm-up time reduce maintenance costs and downtime. Low power consumption extends battery backup time.

• Guaranteed aging rate of less than 5 x 10^-10 per 24 hours
• Well-buffered outputs for added stability
• Battery backup included
• Fast Charge/Float Charge switch
• Compact, light, and rugged package

  Guaranteed aging

  The aging rate is typically reached within 24 hours of turn-on (after 24 hours off). The aging rate after three months of continuous on-time is typically +/- 1 X 10^-10 / 24 hours.

  Well-buffered

  Each frequency output is buffered to provide an output stable to within +/- 2 parts in 10e11, regardless of load changes occurring in any other output frequency. Combined with the quartz crystal stability, buffering between outputs makes the HP 105B suited to frequency standards systems requiring use of multiple frequency outputs.

  Battery

  The HP 105B can be operated from an ac line (115/230V 50-400 Hz) or from an external 22-30V dc supply. It is equipped with a sealed Ni-Cad battery that supplies uninterrupted stand-by power for more than 8 hours, should line power fail.

  Fast Charge

  A switch permits rapid battery recharge after an extended period of battery use.
