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.

(TCP404XL) (500 A DC Continuous)
Key features
Automatic scaling and units
2
- Oscilloscope on-screen readout of
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
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.
