5.6.8.
*OPT? - REPORT AVAILABLE OPTIONS
This query command reports the presence or absence of various options. The format of
the reply is a series of arbitrary ASCII response fields separated by commas. The 6530
will always report the value 0.
5.6.9.
*RST - DEVICE RESET
This command is intended to return the 6530 to a known state, specifically a return to
terse mode. This command will not affect the following:
1.
The output queue.
2.
The state of the IEEE-488 interface.
3.
The selected address of the 6530.
4.
The *SRE setting.
5.
The *ESE setting.
6.
Calibration data that affects device specifications.
The *RST command will perform the following actions:
Clear the key-press buffer.
Make remote responses terse.
Set the measurement units to degrees Celsius.
Set the measurement display to the Aux Channel.
*RST is a MANDATORY IEEE-488.2 command.
5.6.10.
*SRE <u> - SERVICE REQUEST ENABLE COMMAND
The service request enable command allows the 6530 to generate a service request on the
IEEE-488 interface under a limited set of conditions. The limitations on the conditions
are defined by the numeric parameter following the *SRE command. The numeric
parameter is a decimal integer in the range 0-255. The numeric parameter when
expressed in base 2 (binary) represents the bit values of the Service Request Enable
Register. For all bits (except bit 6) a bit value of one (1) indicates an enabled condition
and a bit value of zero (0) represents a disabled condition. *SRE? is the companion query
command.
5.6.11.
*SRE? - SERVICE REQUEST ENABLE QUERY
This command allows a programmer to determine the current contents of the Service
Request Enable Register. A decimal number between 0 and 63 or between 128 and 191
will be returned.
5.6.12.
*STB? - STATUS BYTE QUERY
This command allows the programmer to read the status byte and master summary bits
(shown in Table 5-6.).
