∗RST
Purpose
Resets the MFC-CB settings to factory settings.
Syntax
“∗RST”
Remarks
This command sets the MFC-CB settings to factory settings which is
equivalent to pressing [SPECIAL] on the front panel and selecting
<5Reset>, 1sets. This does not affect the communications or calibration
settings.
Example Command:
Reply:
“*RST”
“OK” (using COM1, no reply if IEEE-488 port)
∗SRE(?)
Purpose Read or set the service request enable register.
Syntax
“∗SRE n”
“∗SRE?”
Parameters
n: ’0 to 255’. This is the decimal representation of the bit(s) to
enable. To allow the MAV and ESB bits to assert the SRQ
line, the argument would be 32 + 16 = 48. Bit 6 (64) is
reserved and cannot be set.
Remarks
The service request enable register determines which bits of the status byte
can set the MSS bit of the status byte and request service by asserting the
SRQ line of the IEEE-488 interface.
Query Reply n (0 to 255)
Example Command:
Reply:
“*SRE 48”
“OK” using COM1, no reply if IEEE-488 port)
Command:
Reply:
“*SRE?”
“48”
∗STB?
Purpose
Read the status byte register.
Syntax
“∗STB?”
Remarks
The status byte register reflects the general status of the MFC-CB. The
‘MSS’ bit state is represented by bit 6.
Query Reply n (0 to 255)
Example Command:
Reply:
“*STB?”
“4”
∗TST?
Purpose
Read the power on self test status.
Syntax
“∗TST?””
Remarks
The MFC-CB system memory stores the user settings (units, mode,
resolution) and retains them when the unit is shutoff. On power up, this
memory is checked. If this memory is corrupted, all user settings are reset
to default (as if the “∗RST” program message was executed), and the ∗TST
query returns a ‘1’. If the MFC-CB passed the test on power up OR if the
∗TST query was used at least once since the unit was powered up, the reply
is ‘0’.
Query Reply “0” or “1”
Example Command:
Reply:
“*TST?”
“1”
