Keysight 16860 Series Portable Logic Analyzers Service Guide 89
Troubleshooting 5
To troubleshoot system power problems
If the system warns you it is powering down before it powers down, it is a fan/overtemp problem. If it
just powers down, it is a power supply problem.
If the lights do not come on and if the system powers up momentarily when you plug it in, make sure
the power button hasn't become jammed or stuck in the pushed-in position.
Power Supplies
All 16860 Series logic analyzers have the same 600 W power supply and a second 15 W power
supply. The power supplies must remain connected in order to test their output voltages. There are
power supply test points on the Frame Interface Board (FIB).
