RF & Telecom Engineering, Testing and Design/Repair

Cablesoft Engineering (CSE) was a RF spectrum analysis,

and telecommunications consulting and testing company.


I'm in the process of shutting the business down in 2023, and this web site will likely completely shutdown (no more downloads) in early July of 2024. However, I still occasionally accept projects in RF spectrum analysis. My 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, and 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 20+ 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, along with optical design and testing.


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. We also perform full 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 primary 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 occasionally take on spectrum analyzer repairs, specializing on the old Avantron/ Sunrise Telecom/VeEX AT2500 series analyzers; however other analyzer brands such as HP/Agilent (primarily the 8590 series) are also repaired. I maintain full laboratory capabilities for testing & repair, calibration, and micro-soldering and micro PCB (SMD) repairs.


At present I have one completely refurbished Sunrise Telecom AT2500RQv3 spectrum analyzer for sale (seller: Achatz4139). This unit is up for auction on Ebay or you can contact me privately for a reduced price. All available options (including the AT-WEB automated testing option) are activated, and I'll ship this unit with a fresh calibration! Contact me or search Ebay if you have questions regarding this unit.
