Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

    The Jitter Transmitter Calibration is semi-automatic and is performed by using a special internal calibration routine and a Spectrum Analyzer. The HP 37717C TX PDH OUTPUT is connected to the Analyzer (via 75 /50 ] Matching Pad) and set to the first calibration point in the routine. With the Analyzer set to display the transmitted data spectrum, a Bessel Null should be observed.
