Part 2: Engineering Function Commands
This section describes the engineering functions which are available in the
DB2000 and DB500 HHP’s and also sets out to demonstrate their use.
Engineering functions are normally hidden from the operator and can only be
accessed by placing the HHP in suspend mode. This can only be achieved by
connecting the HHP to an instrument such as the GSM test jig* or a PC with the
appropriate software**.
*
An upgrade for the GSM test jig is available. This is required because
theDB2000 and DB500 serial interface differs from that of G8/G9.
**
A software package which provides access to the engineering functions will
be available in the near future.
The Engineering functions which are listed here are those which have been
implemented in the GSM Test Jig and are not a complete list of existing
engineering
functions.
ALT_SYNTH
The synthesiser is alternatively programmed between two specified frequencies if
the flag is set. This is disabled through resending the message with the flag field
set to 0.
