Manual

The AM503S is truly a system, consisting of an AM503 Current Probe Amplifier, a TM501 one-wide Power Module, an A6302 Current Probe and Cabling to connect ot any 50 ohm or 1 M ohm input oscilloscope. Options enable you to add or substitute an A6303.
 

Features:

  • Displays Current Signals on an Oscilloscope
  • Current Range, Maximum Current, and Bandwidth Determined by the Probe Used.
  • Allows display of current on any oscilloscope with 10 mV/div sensitivity, 50 ohms or 1 M ohm input.
  • Bandwidth can be set to Full (where it is limited by the probe in use) or to 5 MHz.
  • Coupling can be switch selected to ac or dc.
  • Also see the AM 503B
