Frequency Generator, 1229A

1229A Frequency Generator

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.
