Cablesoft Engineering (CSE) was/is a RF spectrum analysis

and telecommunications consulting and testing company.

Although the business is mostly shutdown, I still accept projects in RF spectrum analysis and testing. At present our lab allows for complete testing from 9 kHz to 6.5 GHz in a variety of areas, including calibrated field strength measurements for radio, television and wireless communications systems, off-air ATSC (8-VSB) testing and reception analysis including computerized reception projections, and RF interference characterization & interference location from 100 kHz to 6 GHz.

Our primary emphasis for the past 30+ years has been to provide Cable Television FCC Proof of Performance testing including NTSC-M analog testing to full FCC Part 76 Subpart K (newest version) specifications & full QAM analysis to ANSI/SCTE 40 2016 specifications. Specialized testing in other fields is available including ATSC high definition television broadcast testing, and consulting services for electric utilities (including municipal) and the cellular industry. My past education and experience include the RF broadcasting (radio and television), the cable television industry, the cellular radio industry, and AC power generation and distribution.

CSE maintains full RF spectrum analysis capabilities from 9 kHz to 6.5 GHz. We have dedicated spectrum analysis equipment specific to RF characterization and field spectrum analysis to 6.5 GHz, along with other spectrum analyzers for specific applications. And we perform antenna, downlead and component testing using VNA (Vector Network) Analysis [Smith Chart parameters {complex impedance, reactance, return loss, etc.}] from 50 kHz to 6.0 GHz.

CSE maintains an office and laboratory located in the scenic Loess Hills of southwestern Iowa, near the greater Council Bluffs, IA - Omaha, NE area.

Many of our activity pages have been removed because my main reason for maintaining this site at present is to continue to provide a (download) source for some of the articles I've written over the years along with other reference material.  I also take on spectrum analyzer repairs, specializing on the old Sunrise Telecom/VeEX AT2500 series analyzers including analyzer calibration; however other analyzer brands such as HP/Agilent (primarily the 8590 series) and Anritsu are also repaired. I maintain full laboratory capabilities for testing & repair, calibration, and micro-soldering and micro PCB (Surface Mount Device) repairs.

At present I have one AT2500RQv3 unit in house and it is under repair. If it becomes available it will include a canvas carrying case as well. More information will become available on this unit once work is complete. For general pricing contact me at the email address below, or visit Ebay and search for units with the seller Achatz4139.
