OPERATION/MAINTENANCE
When connected to a USB port on a PC using a terminal program (such as Hyperterminal), many of the WaveTester’s functions
can be activated from the PC keyboard. The list of functions follows:
Key:
A
Function:
Auto mode
Description:
Pressing the ‘A’ key is the equivalent to holding
on the WaveTester. The wavelength display will begin
toggling between the currently selected wavelength and ‘AUO’. Auto mode scans incoming power for modulated optical signals,
and switches wavelengths automatically when a corresponding modulated signal is received.
Key:
C
Function:
Clear memory
Description:
Pressing the ‘C’ key is the equivalent to holding
on the WaveTester while pressing
to power ON the
WaveTester. The data indicator icon will disappear from the display.
Key:
D
Function:
Download memory
Description:
Pressing the ‘D’ key will download all data into the PC in comma-delimited format. The display will say ‘DONE’
when the download is complete.
Key:
M
Function:
Monitor mode
Description:
Pressing the ‘M’ key will cause the meter to send wavelength and power level information to the serial port. This
data will appear in the terminal window. Monitor mode is useful for checking the stability and power level of a source over a long
period of time. Most terminal programs have a data capture function. Data captured this way can be imported as a comma-
delimited file into a spreadsheet for creating a chart.
Key:
U
Function:
Units set
Description:
Pressing the ‘U’ key is the equivalent to pressing
on the WaveTester. Each time the ‘U’ key is pressed, the
display units will change between dBm, dB, and uW or mW.
Key:
W
Function:
Wavelength set
Description:
Pressing the ‘W’ key is the equivalent to pressing
on the WaveTester. Each time the ‘W’ key is pressed, the
display wavelength will change between the WaveTester’s calibrated wavelengths.
Key:
Z
Function:
Zero function
Description:
Pressing the ‘Z’ key is the equivalent to holding
on the WaveTester. Once the WaveTester display changes
to ‘dB’ units, an optical reference has been set for the currently selected wavelength, otherwise known as ‘zeroed’.
Key:
?
Function:
Firmware version display
Description:
Pressing the ‘?’ button will send the firmware version to the serial port.
