Manufacturer Description:
The TM502A Power Module accepts up to two single width TM 500 plug-ins. This lightweight, portable, benchtop mainframe includes a tilt bail handle and rear panel power entry, switch, and line selector assembly.
Features:
Displays Current Signals on an Oscilloscope
Current Range, Maximum Current, and Bandwidth Determined by the Probe.
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.
Maximum Input Current - 20 A (dc + peak ac) for A6302; 100 A (dc + peak ac) for A6303.
Maximum Voltage for Current Under Test (Bare Conductor) - 500 V (dc + peak ac) for A6302; 700 V (dc + peak ac) for A6303.
Bandwidth (-3dB) - Dc to at least 50 MHz with A6302; Dc to at least 15 MHz with A6303.
Rise Time (Full Bandwidth) - 7 ns or less with A6302; 23 ns or less with A6303.
Deflection Factor - 1 mA/div to 5 A/div for A6302; 20 mA/div to 50 A/div for A6303. In a 1-2-5 sequence for both probes.
The AM503B is a Current Probe Amplifier. The AM503B Current Probe Amplifier is the heart of the AM503S System. The AM503B amplifies and sums the voltage outputs from the transformer and Hall Effect device and outputs it to the measurement instrument. It also provides the Hall Effect Device bias voltage and a reverse "bucking" current that resists saturation of the A6312/A6302/A6303 Current Probe core. The AM503B Current Probe Amplifier replaces the AM503A. All functions are microprocessor controlled, providing a significant improvement in ease of use and functionality. The AM503B uses bright, easy-to-read LEDs to display current/division settings which are controlled with up/down push buttons. A single push button provides both Degauss and auto-balance functions. An additional significant improvement with the AM503B is that individual A6312/A6302/A6303 probes no longer need to be calibrated with a specific amplifier but can be interchanged between AM503Bs and AM5030s. The AM503B and the AM5030 both support the XL Series of current probes. The AM503 and the AM503A do not support the XL Series. The AM503B operates in any TM500/TM5000 power module. The 50 © output of the AM503B can be displayed on any oscilloscope or measurement instrument that has a sensitivity setting of 10 mV/div. A 50 © output cable and termination is included with the AM503B. The scope or measurement instrument requires at least a 400 MHz bandwidth to display the full bandwidth of the A6312 (100 MHz) and 50 MHz for the A6303. You can select either AC only mode or a DC mode which allows you to display a combined AC/DC current signal.
