The Tektronix 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. The AM 503 is a plug-in modular current-probe amplifier that operates in TM 500 Mainframes. It allows display of current/division on any oscilloscope with 10 mV/div sensitivity, 50 ohm or 1 megohm input, and (for performance to full specifications) at least 100 MHz bandpass. The amplifier attenuator is calibrated in 12 steps with a 1, 2, 5 sequence, and the knob-skirt is illuminated to indicate current per division. The current range, maximum current rating, and bandwidth are determined by the particular probe in use. Bandwidth can be set to FULL (where it is limited by the probe in use) or to 5 MHz. Coupling may be switch selected to ac or dc. Ac coupling offers a convenient means of measuring low-amplitude ac signals on a high-level dc current. A front-panel indicator warns of input current overload. ((DC Level Knob; Plastic Case is broken (Cosmetic) but the Knob itself works fine. No Issues with performance)) (Tektronics TM502A w/ AM503 was posted and is owned by: Natalie Becker) |
