The Keysight U1610A/U1620A is a two-channel handheld digital oscilloscope built around a 5.7-inch VGA TFT LCD display and two CAT III 300 V isolated channels for floating measurements. Spanning 100 MHz and 200 MHz bandwidth models, the series combines deep acquisition memory, a fast sampling rate, and an integrated digital multimeter in a portable instrument intended for on-site and field troubleshooting.

The series captures non-repeating events such as pulse-width-modulated circuit behavior, inrush, transients, and motor start-up sequences, holding them over a wider time base for detailed review. Channel-to-channel isolation lets technicians perform floating measurements on signals referenced to different potentials, and the dual-window zoom helps identify problem areas and examine subtle waveform detail and glitches.

ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments listed here are equipment we keep on hand.

Brand Heritage

Keysight Technologies traces its test-and-measurement roots to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999 and then established as Keysight Technologies in 2014.

Compare Other Models in This Series

The U1610A and U1620A make up a two-model family of handheld digital oscilloscopes that share the same VGA display, two isolated channels, integrated multimeter, and data-logging architecture. The models are distinguished primarily by bandwidth and acquisition performance: the U1610A provides 100 MHz bandwidth and the U1620A provides 200 MHz.

Both models carry CAT III 300 V isolated channels and the same 5.7-inch VGA TFT LCD with three viewing modes, so the choice between them centers on the bandwidth, sampling rate, and memory depth a given application requires rather than on feature set.

Each model below links to its own dedicated product page with new condition-matched pricing. Select the model that fits your measurement needs, then choose the available condition and configuration on that model's page.

The two models differ along several measured specifications. The U1610A offers 100 MHz bandwidth, up to 1 GSa/s in single-channel interleaved mode (500 MS/s per channel in dual-channel operation), and up to 120 Kpts record length; the U1620A offers 200 MHz bandwidth, up to 2 GSa/s single-channel interleaved (1 GS/s per channel in dual-channel operation), and up to 2 Mpts record length.

Timebase range and resolution also differ — the U1610A spans 5 ns/div to 50 s/div with 100 ps resolution, while the U1620A reaches 2 ns/div with 40 ps resolution — and calculated rise time is 3.50 ns typical on the U1610A versus 1.75 ns typical on the U1620A. The comparison table below summarizes these differences across the family.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Maximum input voltage: CAT III 300 V on the direct (1:1) scope input, CAT III 600 V with a 10:1 probe; channel-to-channel and terminal-to-earth isolation rated CAT III 300 V.

Important: Warranted specifications are valid after a 30-minute warm-up period and within ± 10 °C of the last calibration temperature; all other specifications are typical.

Important: Keysight recommends using the U1586B temperature adapter for temperature measurement.

Important: AC current measurement requires the U1583B or 1146A current clamp, and DC current measurement requires the 1146A current clamp; these current probes are not part of the standard instrument and are listed under Recommended accessories.

Recommended pairing: add the Keysight U1586B temperature module for temperature measurement, or the U1583B AC current clamp to enable the AC current measurements listed in the accessories.
