A tracking generator option will run an extra $200 and the EMI option, which provides quasi-peak detection and the three EMI bandwidths, is an extra $600. Rigol PSA81 5 – The Rigol DSA815 budget ($1,295) spectrum analyzer tunes from 9 kHz to 1.5 GHz. (A more detailed review and product web page)įigure 8 The new PSA2702T repackaged analyzer with several new features. This truly handheld spectrum analyzer may be purchased for about the monthly cost of renting a bench-top analyzer. Using this low-cost instrument to perform the initial troubleshooting prior to moving the product out to a compliance test facility will save both money and time. Things like markers, peak search, averaging, peak hold, waveform memory, amplitude scale in dBm or dBuV, screen capture and instrument setup memory – not to mention the portability – are very powerful tools for the EMC engineer. While the PSA2701T does not offer the typical EMI bandwidths or quasi-peak detection, it does include a number of very handy features for general EMC troubleshooting.

My favorites include 1 to 30 MHz for conducted emissions, 30 to 200 for low-frequency emissions, 100 to 500 MHz for a lot of my typical troubleshooting and 2.4 to 2.7 GHz for Wi-Fi and Bluetooth sniffing. What I especially like is the unlimited number of instrument setups I can save. Just turn it on and go! I found I could quickly zero in on an emissions issue, even during characterization or pre-qualification testing.įigure 7 The PSA2701T being used to probe for emission leakage.Įmissions can be recorded via screen shots (bmp format) or tables of comma separated variables (csv), which may be saved and imported into your favorite spreadsheet. No more dealing with heavy instruments to lug out to the measurement chamber or open site and no line cords to plug in. Troubleshooting with the PSA2701T and attached probe is fast and easy. What you’re typically looking for is “how much emission is there now, and how much is there once I apply this fix?” 9 kHz, 120 kHz and 1 MHz), I don’t find this to be a limitation during the troubleshooting process. While the unit lacks the standard EMI bandwidths (ex. By attaching a probe directly to the analyzer, you have the perfect handheld emissions detector. The unit is sensitive enough with the 2-turn Beehive loop probes that a preamplifier is usually unnecessary. There are a few key hardware controls, but most are touch-sensitive soft keys. The unit even includes AM/FM demodulator circuitry and an earphone jack at the top for evaluating potential commercial ambient signals.

The Palm uses special software to turn the unit into a fully featured spectrum analyzer. The spectrum analyzer circuitry resides in a fully shielded base section with an SMA connector for the RF input. There’s the possibility you’ll find used units of the older model on eBay for less. While the above models are still available in limited supplies, they are being phased out and replaced with new models PSA1302T ($1395) and PSA2702T ($1695) with the same frequency ranges, but with several new features. The PDA includes all the usual Palm applications, including Wi-Fi, so once you’re done measuring EMC, you can use the unit to check email and browse the Web! The product even comes with the original packaging and accessories for the Palm. In fact, by opening a couple side latches and lifting off the top cover, the PDA simply unplugs from the base unit. If examined closely, you’ll actually observe that the entire user interface – controls and screen – is really an embedded Palm TX PDA. The leather case, which I recommend, runs $137.įigure 6 The Thurlby Thander Instruments, model PSA2701T. by Newark Electronics or Saelig Electronics. This UK-designed analyzer is distributed in the U. It’s truly handheld and will easily fit into a transit case along with your other troubleshooting tools. Many other independent consultants are also using this one. Up to 7.Thurlby Thander PSA2701T – I’ve been using the Thurlby Thander (TTi) PSA2701T for several years now.161 dBm Displayed Average Noise Level (Typ.) Frequency Range from 9 kHz up to 7.5 GHz.
The DSA815 distinguishes between signals with a frequency difference as little as 10 Hz.
The all-digital IF ensures a superior and stable performance. The combination of the widescreen construction, new key layout, and feature set make this spectrum analyzer a great benchtop or field tool, with the digital power to tackle demanding production wireless applications.
