Select laser diode voltage measurement range
[:UPPer] <n>
[:SENSe[1]]:VOLTage[:DC]:RANGe[:UPPer] <n>|UP|DOWN Select laser diode voltage range
Parameters
<n> = 0 to 10.5 Expected reading in volts
DEFault 10
MINimum 0
MAXimum 10.5
UP Select next higher measurement range
DOWN Select next lower measurement range
Query

:RANGe? MAXimum Query highest range
Description
This command is used to select the measurement range for the laser
diode voltage measurement. The range is selected by specifying the
expected reading. The instrument will then go to the most sensitive
reading that will accommodate that reading. For example, if you expect
a reading of approximately 7V then simply let <n> = 7 in order to select
the 10V range.
You can also use the UP and DOWN parameters to select range. Each
time UP or DOWN is sent, the next higher or lower measurement range
is selected. When on the maximum range, sending UP is a No-Op (no
operation). When on the lowest range, sending DOWN is a NO-Op.
Select detector current measurement range
