The SDU5600 is the next generation in spectrum display units. Using a five-inch TFT color display, DSP and FFT (Fast Fourier Transform), faster sampling rates and color imaging, the SDU5600 opens the door to new possibilities and applications.

MEILI SM5010: I use mine for finding and identifying unknown signals (it has audio output!), optimizing antennas, and as a spectrum display unit with my wide-coverage receiver. This is the most cost-effective instrument available.
 

The SM5010 spectrum analyzer is indispensable for viewing an entire block of radio spectrum, revealing unknown signals. Choose small segments under 1 MHz wide, or step sequentially up to a giant swath of more than 1 GHz , observing all signals in the spectrum.

MASTECH multimeter: This meter continues to amaze me with its enormous number of useful functions. Even Judy uses it for environmental control growing orchids!

Nothing comes close to the multiple functions of the MS8209 with its “5 in 1” concept to measure sound level, light intensity, humidity, temperature, and electrical measurements including AC and DC volts, current, resistance, frequency and capacitance.

The WiNRADiO ERD-1500 Electromagnetic Radiation Detector is an exceptionally efficient "RF Sniffer" developed to quickly and reliably locate sources of electromagnetic interference. The detector contains a miniature wide-band antenna with a quality amplifier and high-performance Schottky barrier detection diodes for maximum sensitivity.

WinRadio products are available only to customers in the U.S. and Canada.

The shirt-pocket MFJ-886 offers 1 MHz-3 GHz frequency range, a 100 MHz sensitivity of 0.8 mV and readout to 1 Hz, all from a large (3/4"H), 10-digit LCD!
