HP 70310A Precision Frequency Reference
The HP 70310A precision frequency reference provides a frequency reference for HP 70000
modular measurement instruments and other instruments . The module provides two
references , 10 MHz and 100 MHz, which are produced by a phase-locked, ovenized oscillator .
An external reference input is available for applying a house standard to your spectrum
analyzer . An option adds two isolated distribution ampliers with three outputs each leveled
to 0 dBm. Each amplier input accepts a 04 to 4 dBm signal from 5 MHz to 300 MHz. Use the
distribution ampliers to distribute the phase-locking, 300 MHz frequency reference (normally
produced by the local oscillator module) to multiple RF sections , tracking generators , or
external-mixer-interface modules .
An accessory power pack is available for maintaining the operation of the ovenized oscillator
when power is removed from the HP 70001A mainframe .
