CQS-4 C-Quam Synthesizer
Delta Electronics
The Model CQS-4 incorporates a high output amplifier and 63 dB programmable attenuator to increase the capabilities over earlier versions. The CQS-4 and earlier models are currently used in testing stereo decoder integrated circuits, calibrating modulation monitors, production testing of C-QUAM receivers and as a primary reference for the manufacture of C-QUAM stereo exciters.
SM-1
Delta Electronics
The Model SM-1 Splatter Monitor provides AM broadcast engineers with a means of accurately and easily measuring off-channel emissions to ensure compliance with the FCC (NRSC-2) emissions standard. Manufactured in response to the recommendations of the National Radio Systems Committee (NRSC) for AM improvement, the instrument provides many of the features of an expensive spectrum analyzer at a significantly reduced price.

SNG-1 Stereo Noise Generator
Delta Electronics
Although a variety of noise generators are available, pricing and features vary widely. Many generators offer portability and low cost at the expense of accuracy. More expensive "laboratory" type noise generators offer high performance and more features, but are often beyond the budget of the broadcast or recording facility. The Delta Model SNG-1 Stereo Noise Generator offers a number of "laboratory" type features and noise weightings in a very affordable and compact package.

Toroidal Current Transformers
Delta Electronics
The TCT series of precision toroidal current transformers provides sample voltages for RF current phase and magnitude measurement on broadcast antenna arrays. The transformers are available with center conductor voltage ratings of 10 kVRMS, 20 kVRMS or 42.4 kVRMS for use with low to high power antenna arrays and standard to high impedance antennas. The transformer may be combined with any of Delta's standard TCA-N-EX or TCA-N-EXR single scale or TCA-N/N-EXR dual scale RF ammeters for precision RF current measurements.
