Module Description
Providing an External Clock
You can program the HP E1433A to accept an external word rate clock from the Sample 0 line on the VXI Bus. The digital filters are still functional, providing a range of effective word rates. All sampling is done simultaneously and is not multiplexed.
To connect an External Sample Clock, use the External Sample SMB connector on front panel of the HP E1433A. External Sample at word rate and External Trigger are available on the front panel of HP E1433A’s which do not have an arbitrary source or tachometer option.
The external clock must be a fixed frequency. Its maximum frequency must not be higher than 100 kHz. Its minimum frequency must be at least 40.96 kHz.
