Steps to remove the browser from the ergonomic handle Handling SMA probe heads The U1818A/B probe amplifier can become damaged when used with the N5380A or E2695A SMA probe heads. Use the Keysight N5380-64701 SMA Head Support to prevent damage. Make sure to plug the probe amplifier into the SMA head before installing the SMA Head Support and do not attempt to plug or unplug the SMA head from the probe amplifier while it is in the SMA head support housing. -
