Tektronix TCPA300 Probe Amplifier for TCP312A, TCP305A and TCP303 Current Probes, up to 100 MHz

Name: Tektronix TCPA300 Probe Amplifier for TCP312A, TCP305A and TCP303 Current Probes, up to 100 MHz
SKU: LIH-TCPA300
Availability: InStock

The Tektronix TCPA300 probe amplifier runs three Tektronix current probes: the TCP312A, TCP305A and TCP303. With the TCP312A, the system reaches up to 100 MHz. Order the probe as a separate line.

Category: Oscilloscope probes

Description

Fast switching stages need a current probe that keeps pace with their edges. The Tektronix TCPA300 probe amplifier is a current probe amplifier: it powers a clamp-on probe and turns its output into a scaled signal for an oscilloscope. It accepts three Tektronix probe heads, so one box can serve several jobs. Lost in HCM rents and sells it in Vietnam and arranges service on request.

Three probe heads to choose from

The listing names the TCP312A, TCP305A and TCP303 as compatible. Each head has its own current range and bandwidth, so the probe you plug in sets what the system can do. Because no probe ships with the amplifier, decide which head fits your job first. Then add that probe to the same quote.

Where the 100 MHz figure comes from

The source gives DC to 100 MHz as the system capability. However, it ties that figure to the TCP312A. With the other two heads, check their own limits in the Tektronix datasheet before you rely on a number. In other words, treat probe and amplifier bandwidth as one pair, not as two separate specs.

Jobs that suit the Tektronix TCPA300 probe amplifier

Power supply design: inductor and switch currents in DC/DC converters.
Motor drive work: phase current next to gate signals on the same screen.
Inrush and start-up checks on boards and modules.
Teaching labs that share one amplifier across several probe heads.

Connection order

Clamp the probe around one conductor, then plug it into the amplifier. Next, route the TCPA300 output to a compatible oscilloscope interface or a properly terminated input. After that, degauss and zero the system if the manual calls for it. Finally, confirm that the scale on screen matches the probe range you chose.

A project rental covers a design review or a short compliance push. A purchase suits a power lab with steady demand. Send the scope model, the probe head you need, the expected current and the frequency, then get a quote from Lost in HCM for the Tektronix TCPA300 probe amplifier.
