Test-and-measurement company Aspen Electronics is rolling out a Model GW Instek GSP-827 General Purpose Spectrum Analyzer. It uses a 640 x 480-pixel non-color LCD, and can communicate across an RS-232 line.

Covering a frequency range of 9kHz to 2.7GHz, the GSP-827 can be used for both development work and in production. When equipped with an internal battery, GSP-827 analyzer also lends itself to maintenance and installation of on-site wireless systems.

Built-in Tracking generator

Equipped to make ACPR, OCBW and channel power measurements, the box can also be equipped with an optional tracking generator with a normalized output.

Other features include the ability to accommodate inputs from -105dBm to 20dBm (inputs are overload protected), and split window operation that supports simultaneous measurements in two separate frequency spans. Resolution bandwidth can be set for 3kHz, 30kHz, 300kHz or 4MHz. The analyzer can also be used with external reference clocks between 1MHz and 19.2MHz.

Users also get ten markers (delta mode, peak search, peak track) and trace functions. The latter gives dual-trace displays, peak hold/freeze/average capability and trace math. A user can also set upper/lower limit lines, which is useful for Pass/Fail tests. Finally, the lightweight analyzer also touts 100 trace/state memories with date and time stamping and file names.
