ILX Lightwave LDC-3700 Series User Manual

e. After a few seconds, the LDC-3700 Series Laser Diode Controller will be ready for the actual laser voltage
to be entered (in volts) via the "LAS:LDV" command. The measured value of the voltage should not
be
entered until the LDC-3700 Series Laser Diode Controller is ready to receive it. The LDC-3700 Series
Laser Diode Controller will beep when it is ready to accept a new calibration value.
The LDC-3700 Series Laser Diode Controller will
be ready to receive the voltage value when, after a
"LAS:CAL:LDV?" query is sent, the response from the LDC-3700 Series Laser Diode Controller is "1".
f. Once the actual voltage value is entered via the "LAS:LDVN command, the LDC-3700 Series Laser Diode
Controller will set the current to approximately one-fourth of the original value. It will then expect the
second calibration voltage point, approximately one-fourth of the original voltage. (For example,
if the
first calibration set point was 6.0000
V, the second set point will be about 1.5000 V.)
g. Input the second actual (measured) LASER output current (as an <nrf value.) as in Step d.
h. Once the second actual voltage value is entered via the "LAS:LDVn command, the LDC-3700 Series
Laser Diode Controller will beep and the new calibration constants will
be calculated and stored into non-
volatile memory.
The operation complete flag (bit 0 of the Standard Event Status Register) may
be used to trigger a service
request. This type of interrupt is enabled by setting bit 0 of the Service Request Enable register (via the
*ESE command) and bit 5 of the Service Request Enable register (via the *SRE command). Service
request
(SRQ) handling depends on your GPIB hardware. Refer to your GPIB user's manual for details.
6.5 Fuse Replacement
Thc fuses are accessible from the back panel of the LDC-3700 Series Laser Diode Controller. Before replacing the
fi~scs. turn power off and disconnect the line cord. Use only the fuses indicated below in Table 6.2.
