AC/DC Current Measurement Systems

TCPA300, TCP312A, TCP305A, TCP303, TCPA400, TCP404XL Datasheet

The TCP300 and TCP400 Series AC/DC current measurement family is a

highly advanced current measurement system for today's current

measurement needs. When connected to Tektronix oscilloscopes with

TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC)

interfaces, current measurements and calculations are simple and easy.

Key performance specifications

DC - 100 MHz, Current Probe Amplifier (TCPA300) uses:

DC - 100 MHz, 30 A DC (TCP312A)

DC - 50 MHz, 50 A DC (TCP305A)

DC - 15 MHz, 150 A DC (TCP303)

DC - 50 MHz, Current Probe Amplifier (TCPA400) Uses:

Key features

magnitude and amps reduces measurement errors with no more hand

calculations

AC/DC input coupling

Low insertion impedance reduces device under test loading

Split-core construction allows easy circuit connection

Status indicators provide visual operating status and notification of

potential error conditions - degauss, probe open, overload, not

terminated into 50 Ω, noncompatible probe type

Low DC drift and noise allows improved low-level current

measurements

3rd party safety certification

with TCA-BNC adapter

Applications

Development and analysis solutions for designers, installers, and

service personnel in telecom, data comm, computer, and

semiconductor power electronics environments for:

Power supplies (switching and linear)

Semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs)

Power inverters/converters

Electronic ballasts

Industrial/consumer electronics

Mobile communications (phone, satellite, relay stations)

Motor drives

Transportation systems (electronic vehicles, electric trains, locomotives,

avionics)

Meets today's AC/DC current measurement

applications

The TCPA300 amplifier, when used with TCP312A, TCP305A, or TCP303

probes, provides a wide range of current measurement capability and spans

the gap between low-level milliamp measurements to very high current

levels. These three probes provide current measurement capabilities of

30 A, 50 A, and 150 A DC continuous. For even higher current levels, the

TCPA400 amplifier with the TCP404XL current probe measures 500 A DC

continuous and 750 A DC continuous, derated with duty cycle.

Higher-frequency performance is available with the TCP312A w/TCPA300

providing ≥100 MHz bandwidth and a maximum current of 30 A DC.
