1229A Frequency Generator/Micro Phase Stepper

The ptf 1229A utilizes the latest technological advances in precision frequency synthesizers to provide a multiple output, wide range, high precision frequency reference instrument, capable of delivering frequencies over the range of 0.1Hz up to 30MHz with a resolution of 0.1 Hz over the full range.
The unit includes an external reference input to allow extremely high accuracy outputs at precisely the frequency required, together with a front panel indicator to verify “lock” to the external reference. The standard unit includes two independent frequency outputs of any frequency within the range, and provides both sine and square wave outputs for each frequency.
An expansion module gives the capability to increase the number of independent frequency outputs up to a total of four frequencies, with sine and square wave outputs for each, giving a total of eight outputs.

Additionally the unit provides a capability to inject phase changes on the output with a resolution of 1ns. Set up allows either advance or retard of phase.
The unit includes full remote monitoring/control interfaces with the standard ptf menu system including expanded help on each command, RS232/USB, and Ethernet interfaces with telnet, and web browser protocols. For local front panel
control the unit has an easy to use front panel keypad and high brightness vacuum fluorescent display that allows parameter setting through a menu system, and status monitoring with multiple status screens available on the highly visible display.
The estimated MTBF of the unit is >300,000 hours, but for applications requiring even greater reliability, the unit offers an auto switching input option, allowing two independent references to be connected to the unit.
