Troubleshooting Guide
Below are some frequently asked questions and answers. Please check if any apply to your instrument
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 Input Power Requirements”.
Q: I do not get any output from the output terminals
-
Make sure that the
On
button(s) above channel 1 and/or channel 2 BNC connectors are lit. If not, press
it once to toggle the output option
ON
. The backlight of these output channel 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. Refer to section “2.2 Output Connections”.
Q: My two signals are out of phase even after I press the sync phase button.
-
Check that the two cables being used are the same impedances. At higher frequencies, impedances of
the cables play a factor in the signal integrity.
-
Check that the two cables being used are the same exact lengths. At higher frequencies, different
length cables will cause phase delay issues between the two channels.
