AD2201 200 MHz active differential probe, BNC

The AD2201 is a 200 MHz bandwidth active differential probe suitable for high-speed measurement applications, with a differential measurement range of ±20 V and a common-mode range of up to ±60 V (DC + peak AC). 

This differential probe extends the functionality of standard single-ended input oscilloscopes to allow a safe and accurate method of making differential voltage measurements. Applications include making safe measurements in power circuit applications and acquisition of high-speed balanced differential signals found in serial communications buses such as BroadR-Reach (see application note).

Recently redesigned, the AD2201 replaces the TA045 with the same performance specifications, but with improved powering options. This probe now includes an in-line battery module, with a 5 V USB power lead integrated for use with standard off-the-shelf USB chargers.

The kit includes the following items:

  • AD2201 probe
  • Test hooks, pair, red and black
  • Crocodile clips, pair, red and black
  • 9 V battery
  • USB power cable (mains adaptor not included)
