The CW503 provides a handy power supply for both the differential probe and the LNA. Multiple probes can be connected to a single power supply. The following shows the internal block diagram of the CW503 probe power supply: See [[Filehttps:blockdiagram.png|image]] The use of isolated DC-DC converters allows you to use connected probes without worry about ground loops. Note the probe is ''not designed'' for use at high isolation voltages (>30V). The power supply uses a micro-USB jack, allowing you to power the probe from front-pane USB ports on some instruments (be careful of current limits if using this method): [[File:diffprobe-psu.jpg|400px|image]] Alternatively the probe comes with a high-quality 5.0V wall-wart adapter, which has been selected for minimum noise input to the CW503. == Front-Panel Connections == The following can be found on the front panel of the device: <ul><li><p>Power Good LEDs:</p><blockquote><p>The probe PSU monitors the +7/rtfm.8V, -7.8V, and +3.3V outputs. If these outputs fall below the required setpoints the LEDs extinguish.
