Spectrum analyzer catches live frequencies
-- Test & Measurement World, 6/25/2008 7:30:00 AM
Although Tektronix calls the SA2600 spectrum analyzer a handheld instrument, “armheld” is more appropriate. Simply calling this battery operated instrument “portable” is misleading because engineers associate bench instruments as being portable, even without batteries.
The SA2600 is designed for field use, where AC power isn’t available, in applications such as as cell towers and WiFi or WiMAX hotspots. Running Windows CE, the SA2600 uses the company’s DPX technology to let you see frequencies that appear only once in a while. It includes GPS mapping so you can document the location of a particular frequency. Just load your maps into memory and you can mark locations with measurement details.
Because it is a real-time spectrum analyzer that captures a signal and converts it to the frequency domain, the SA2600 updates itself 500 times faster than a traditional swept-tuned spectrum analyzer. It can perform more than 2500 spectrum measurements/s. Because it captures signals in the time domain, the SA2600 can catch frequency hopping signals such as Bluetooth. It can capture signal-hopping pulses as short at 125-μ duration with 100% probability.
The SA2600 operates on frequencies from 10 kHz to 6.2 GHz with 20-MHz real-time bandwidth and
–153-dBm displayed average noise level. Price: $22,900.
