Updating the Sub-VI

Press the white arrow located in the toolbar of the Front Panel and the Block Diagram to execute the
sub-VI. To execute a sub-VI means to update the instrument with values input by the user or query
the instrument. If there is not a white arrow, but a broken gray arrow, see the Errors.

FPM-8220 Sub-VI Descriptions

FPM-8220 Read Instrument ID

Queries the instrument with the IEEE 488.2 command *IDN? and returns the manufacturer,
model number, serial number and firmware version number as a string.

FPM-8220 Read Errors

Reads the instrument's error queue and returns it as a string. See the FPM-8220 Manual for more
information.

FPM-8220 Read Head ID

Queries the instrument with the command SLOT:HEAD:IDN? and returns the connected
measurement head manufacturer, model number, serial number and firmware version number
as a string. If no head is connected, the returned string will be "No Head Connected". There is
also a boolean return value that indicates whether or not a head is connected. This value can
be useful for control logic that depends on the presence of a head.

FPM-8220 Set/Read Brightness

Sets or read the brightness of the instrument's physical front panel display. The brightness is an
integer, range 1-10.

FPM-8220 Set/Read Display Enable

Sets or reads the display enable control using a boolean. This will turn on/off the instrument's
physical front panel display.

FPM-8220 Set/Read Filter

Sets or reads the instrument's filter rate. The input to Set Filter is an enumerated value that can be
either SLOW, MEDIUM, or FAST. Read filter returns the filter rate as a string.

FPM-8220 Read GPIB Address

Reads the GPIB address and returns it as an integer.

FPM-8220 Set/Read Mode

Sets or reads the instrument's current measurement mode. The input to Set Mode is an enumerated
value that can be W, DB, or DBM. Read Mode returns the measurement mode as a string.

FPM-8220 Read Power

Reads the current measured power as a floating point number.

FPM-8220 Set/Read Radix

Sets or reads the current radix for remote number entry and display. The input to Set Radix is an
enumerated value that can be DEC, HEX, BIN, or OCT. Read Radix returns the radix as a string.
