F.W. BELL Model 7030 Gauss/Tesla Meter Instruction Manual
Section 7 – Remote Operation 7-39
SCPI COMMANDS-
HOLD COMMANDS
(Continued) :CALCulate#:HOLD:VALLey:STATe <b>
The VALLEY HOLD function is turned on when <b> is “1” or “ON”, or
turned off when <b> is “0“ or “OFF”.
:CALCulate#:HOLD:VALLey:STATe?
The state of the VALLEY HOLD function (“OFF” or “ON”) is placed in the
output queue.
:CALCulate#:HOLD:VALLey:CLEar
The value being held by the VALLEY HOLD function is reset to 0.
:CALCulate#:HOLD:VALLey?
The value being held by the VALLEY HOLD function is placed in the
output queue and will be between 0.0000000000 and
±
29999999. The
meaning of this value depends upon the currently selected unit of
measure (gauss, tesla, etc.). For instance the value -1.0203 could mean
-1.0203 G or -1.0203 T.
SCPI COMMANDS-
MEASUREMENT
COMMANDS Since these commands are channel-specific the “#” in each command
should be replaced with the channel number 1,2 or 3. If the channel
number is omitted then Channel-1 is assumed.
:MEASure#:FLUX?
The latest flux density reading is placed in the output queue and will be
between 0.0000000000 and
±
29999999. The meaning of this value
depends upon the currently selected unit of measure (gauss, tesla, etc.).
For instance the value 1.0203 could mean 1.0203 G or 1.0203 T. The
rate at which flux density readings are updated is specified in the FILTER
menu (or by using the CALCulate:AVERage:COUNt command). Issuing
the MEASure#:FLUX? command at a rate that is faster than this update
rate will return the same reading multiple times. For instance, if the
meter updates the reading once per second, and the MEASure#:FLUX?
command is issued 10 times per second, the same reading will be
returned 10 times. To avoid this the Reading Available (RAV) status bit
in the Measurement Event Register can be monitored to determine when
a new reading is available.
