Calibration
To allow calibration, the unit must be connected to the computer and the
supplied software must be installed. Please consult the ‘Getting Started’ manual
for details on the connection and installation procedure.
Select the function generator module [Function generator].
Select the correct parallel port [Options > Hardware setup].
Check if the ‘POWER ON’ (LD1) LED lights. If it does not light, check the
complete assembly and check the parallel port settings in the options-hardware
setup of the software.
Make sure the frequency is set to 1000Hz (1KHz). Adjust if necessary (
1
).
Make sure the offset is set to 0V. Adjust if necessary (
6
).
Make sure the amplitude is set to 5Vpp. Adjust if necessary (
7
).
Select sinewave output (
4
). Readout (
9
) should now show a sine wave and the
‘READY’ LED (LD2) should light.
Connect a digital multimeter to the ‘signal out’ connector of the generator. Set it
to DC volts. Adjust the multi-turn trimmer RV1 until the multimeter displays zero
volts. If necessary, adjust the range of the meter to obtain a higher resolution.
Now you can check the waveform, using an oscilloscope or one of our PC- or
handheld scopes
If for some the measured values are totally off, please inspect the complete
assembly, paying special attention to the solder joints, component positioning and
values.
If everything went well, you can fasten the PCB with the supplied screws, and
close the enclosure lid.
Your
function generator is now ready for use !
