Hameg/Rohde & Schwarz entry-level, mixed-signal scope offers “exceptional features”

September 12, 2014 // By Graham Prophet
Fanless operation, 1Mpoints of memory depth and a 1 Gsample/sec realtime sampling rate are the key features of the R&S HMO1002 mixed signal oscilloscope. With a vertical sensitivity of 1 mV/div and integrated 128 kpoint FFT, the instrument has a high specification for the “three-figure price segment”.

Target users include embedded developers, service and maintenance technicians and users in the education sector. The R&S HMO1002 series mixed signal oscilloscopes, developed by Rohde & Schwarz subsidiary HAMEG Instruments, can be expanded at any time from 50 MHz to 70 MHz or 100 MHz bandwidth by means of a simple upgrade option. HAMEG recently introduced a practical upgrade voucher for all of its instruments, and it is now also available for the R&S HMO1002.

The HMO1002 includes mixed signal functionality. Measuring analogue and digital signals simultaneously may not be anything unusual for an oscilloscope these days, but it is, says the company, for a T&M instrument in the three-figure price segment (which we take to mean, below-€1000). Fanless design of the R&S HMO1002 is ensures quiet operation and makes the instrument less susceptible to faults. The oscilloscope's antiglare display takes up approximately 40% of the front-panel area and is easy to read. A logic probe can be connected to the front panel.

An integrated pattern generator enables professional embedded developers to program protocol messages at up to 50 Mbit/sec. This makes it possible, for example, to emulate circuit components that are still under development. Two kbit are available per channel for the signal patterns generated. The 4-bit counter output (adjustable up to 25 MHz) allows developers to use the pattern generator as a clock source. The instrument's high signal update rate of up to 10,000 waveforms/sec makes it possible to measure signal deviations with precision. It also offers mask-based pass/fail testing.

A three-digit digital voltmeter integrated into the scope makes it possible to perform voltage measurements simultaneously on both analogue channels, with two user-definable parameters each. The digital component tester helps service technicians check the functionality of capacitors, coils and semiconductor elements quickly and easily.

Teaching staff in the education sector will find the education mode in the R&S HMO1002 useful. All of the fully automatic analysis tools that
