Spectrum Analysis, Up To 13.5 GHz
S930901B
-
The S930901B spectrum analysis adds high-performance microwave spectrum analysis to the PNA family up to 13.5 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Simultaneous spectrum measurements can be done using up to five test and reference receivers. This multi-channel SA can be used with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.

Quad RF Driver
-
The Quad RF Driver contains four independent RF channels, each with an RF synthesizer, variable attenuator, and 1W power amplifier. The RF signal can originate from either the internal synthesizer or an external source via SMA input. All channels have independent frequency, phase, and gain settings and can be operated in one of two modes. The “Wideband” mode operates from 35MHz to 2GHz with a 3.472KHz resolution; over this range the frequency roll-off is approximately 0.5dB/100MHz. “Int-N Phase Adjust” mode allows the user to set and maintain a fixed phase relationship between all four channels. This mode is designed to operate between 300 and 460MHz with a 2MHz resolution. Two additional inputs are provided for an external frequency reference and digital modulation.

1000W Ferroresonant Power Supply
Series PRR
-
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.

Ionic Contamination Test Systems
CM+ Series
-
The Contaminometer (CM+ Series) system was originally developed by Protonique, the business of industry guru Brian Ellis. They also featured in the early development programmes of "cleanliness measurement" carried out by the US Department of Defense at China Lake in the 1970s. Historically, International Standard IPC-J-STD001 stated that assemblies be cleaned to a value of <1.5µg/cm2 of NaCl equivalence. However, the new design is linked to the introduction of the new process control metric introduced by Gen3 Systems: Process Ionic Contamination Testing. The CM+ Series measure the amount of ionic contamination in accordance with all existing test methods, often referred to as ROSE testing, as well as the new PICT test.

The EM-2107A is a standard test fixture for evaluation of the electromagnetic shielding effectiveness of planar material. The fixture is an enlarged section of coaxial transmission line and complies fully with the requirements of ASTM test method D4935-1. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred. The EM-2107A is provided with a reference standard test specimen, a dynamic range specimen. Dynamic range of greater than 80dB is achievable, although the cables and other test system components usually establishes the limiting factors.
