There are six user-defined front panel instrument presets, in addition to the unlimited ones saved to memory. Instrument setups and screen captures may be saved to either an external memory stick or internal memory. To save screen captures (.bmp format), plug in a memory stick to the front USB port and press the “Print” button on the left side of the display. This would avoid having to rotate through English and Chinese mode every time you went to enter a file name. One other improvement might be to define the local language in an overall user setup. It would be nice to be able to plug in a keyboard for that purpose, though. The method for naming files is somewhat like entering text on regular (non-“smart”) mobile phones and is fairly quick once you get the hang of it. It's relatively easy to save screen captures and save/recall instrument setups. Rigol has a downloadable app-note describing the purpose of each in more detail.Īlthough advertised at “up to -135 dBm displayed average noise level (DANL)”, in practical use, it was more on the order of -60 to -90 dBm, depending on the frequency span and resolution bandwidths invoked. The quasi-peak detector is described more fully in the EMI option below. These include positive peak, negative peak, sample, normal (the default), RMS average, voltage average and quasi-peak (optional). The cooling fan is audible but not distracting. Table 1 – Comparison of the Rigol DSA815 with the Agilent N9000A CXA analyzer.īoot-up time is just 17 seconds, much faster than Windows-based instruments. As you can see, the Agilent beat the Rigol technically (as expected) in all areas. In all cases, I tried to compare specs for the Agilent up to an upper frequency of 1.5 GHz. I compared some of the most important DSA815 specs with Agilent Technologies most comparable analyzer (but at 10X the cost) – the model N9000A CXA (9 kHz to 3 GHz).

Ultra Spectrum (PC) software option (provides additional analysis, including a waterfall display).8-inch WVGA (800×480) display (600 pixel waveform resolution).Connectivity: LAN (LXI standard), USB host, USB device, GPIB (option).VSWR measurement kit option (1 MHz to 2 GHz).EMI filter and quasi-peak detector option (200 Hz, 120 kHz and 1 MHz BWs at -6 dB).

1.5 GHz tracking generator option (-20 to 0 dBm).

-80 dBc/Hz at 10 kHz offset phase noise.

Video bandwidth (1 Hz to 3 MHz at -3 dB).

Resolution bandwidth (100 Hz to 1 MHz at -3 dB).

Up to -135 dBm displayed average noise level (DANL).

The line power is universal and can take 100 to 240 VAC at 45 to 440 Hz. It also includes a Kensington® security slot. In addition, there are rear BNC ports for Trigger In, 10 MHz Out and 10 MHz In. There is a USB-B 2.0 port on the front and USB-A 2.0 (printer) and Ethernet (10/100 Base-T) ports on the rear. The most used controls are all one or two button-presses away. There's also a “Help” key that will describe each control for you. Down along the left side of the display you'll find a column of analyzer status icons. A vertical row of soft-keys are used to select secondary functions. I loved the large color screen (800×480 WVGA). Besides the usual frequency, span and amplitude buttons, major groupings include control, marker, measure, utility and Edit (numeric and text input).

The controls are arranged in logical groupings, duplicating to a large degree those found on Agilent spectrum analyzers.

The “key points” throughout the manual were welcome aids to my understanding. I added the guide to my iPad for easy reference.Įven better, the table of contents and index are all hot-linked to their corresponding sections of the user guide.

However, the actual user guide is supplied on CD or available as a download from their web site.

The Quick Guide brochure explained how to adjust the front legs, connect it to power, do an initial self-calibration, and the layout of the controls and ports, but little else. Yes, I am that old! I’m hoping Rigol will supply us a proper case in the future. It rather reminds me of the old-time doctor’s kits when they used to make house calls. I do love the rounded “lunchbox” style case. The front pouch is large enough to carry an assortment of cables and adapters and the rear compartment fits the line cord nicely.

I also noticed (painfully) the front snap-clips that hold the cover closed will pinch your fingers, if held on the sides while snapping them closed. The carry case is well made and nicely padded, but was originally designed for their 1000-series oscilloscopes, so it's a very tight fit for the wider analyzer and the “hold-down” straps don’t fit all the way across the top.
