Oscilloscope/multimeter

The Owon HDS1022M and HDS2062M two-channel, digital oscilloscope/multimeters are designed for field use including power applications permitting a maximum voltage of 400 V peak.

The instruments have an analog bandwidth of DC to 20 MHz (HDS1022M) and 60 MHz (HDS2062M) and maximum sampling rate of 100 MS/s (HDS1022M) and 250 MS/s (HDS2062M).

Both channels feature an 8 bit A/D converter providing synchronous sampling, have a 6 kW data record capacity and use an interpolation function between data points of sin x/x.

Scanning speeds range from ns/div to 5 s/div. Vertical sensitivity ranges from 5 mV/div to 5 V/div and both AC and DC input modes are available.

The triggering system supports NTSC, PAL and SECAM. Post- and pre-triggering is provided (655 divisions for pre- and four divisions for post-triggering).

Mathematical functions include DV and Dt, peak-to-peak, average and RMS value as well as frequency and period measurement. The multimeter feature makes use of the oscilloscope display to show analog meter-needle readouts to provide an instinctive feel to the measurement while showing a digital value at the same time.

Parameters measured include AC and DC voltage (1000 VDC; 750 VAC - RMS equivalent), current (to 20 A AC), resistance (to 40 MW), capacitance (to 100 µF) and diode function.
