The AEMC OX7202III and OX7204III oscilloscopes are rugged, self-contained, hand-held, two or four-channel oscilloscopes with 100 or 200 MHz bandwidth. The OX7202III and OX7204III feature 0.1% accuracy and a maximum input voltage of 600 V DC, 600 V RMS, 850 V pk (DC + peak AC at 1 kHz) without a 10/1 probe and 1000 V RMS with a 10/1 probe. In addition to oscilloscope functions, the OX7202III and OX7204III also include an FFT analyzer, TRMS multimeter, harmonic analyzer and a recorder making them the perfect tools for both laboratory and field testing.

The OX7202III and OX7204III utilize the patented system of "plug- and-play" accessories, individual isolation of each of the measurement channels and a range of remote management capabilities. The Ethernet link lets usersremotely control the oscilloscope without loading any software to a PC.

The AEMC OX7202III and OX7204III oscilloscopes feature multi-interface communication connectors; RS232, Centronics and Ethernet. In oscilloscope and recorder modes the meters have memory for up to 50,000 points per channel.
