4 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
-
Check that the power cord is securely connected to the AC input and there is live power
from your electrical AC outlet.
-
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
-
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
-
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.
