Troubleshooting Guide
Below are some frequently asked questions and answers. Please check if any apply to your
power supply before contacting B&K Precision.
Q: I cannot power up the generator
o Check that the power cord is securely connected to the AC input and there is live power
from your electrical AC outlet.
o Verify that the AC power coming from the mains is the correct voltage. The generator can
accept a specific range of AC input voltages. Refer to section “2.1”.
Q: I cannot see any output out of the output terminals
o Make sure that the Output buttons above channel 1 and/or channel 2 is lit. If not, press it
once. The backlight of these Output buttons indicates that the respective channel’s output
is enabled.
Q: I have connected my signal to an oscilloscope, but the amplitude is double of what I set
o This is often because the impedance of the generator is not matched with the oscilloscope.
When the generator is set to 50 Ω impedance, connecting it directly to an oscilloscope with
a 1 MΩ input impedance will cause this to happen. To eliminate this issue, connect a 50 Ω
terminator to the input of the oscilloscope, then connect a BNC cable between the
generator and the terminator to have matching impedance.
