The Mag Lead
136
-
*Mag Lead features a magnetic disconnect near the test probe end. *Just disconnect the test probe and you can “stick” to any metallic ground or test point. *Quit fumbling with alligator clips that fall off - Mag Lead’s powerfull magnet will hold tight! *This is a time saving tool - if you don’t have to walk to your tool box to retrieve your alligator clips, even on just half the occasions, then you’ve saved time. *Very helpful for automotive reference points and troubleshooting. *Can eliminate the need to hold probes while checking or monitoring a signal. *Two high power, low resistance magnets hold the probe to the lead. *Fits almost all Digital Multimeters and can be used with hand-held scopes too. *Get the Mag Lead, it stays put and won’t fall off, like alligator clips do!

34MHz to 4.4GHz Frequency Synthesizer
-
A serial controllable synthesizer that will output any frequency between 33MHz to 4.4GHz. Arduino Pro Mini + ADF4351. It's a frequency generator that you control using serial commands. The synth has a built-in pre-programmed Arduino Pro Mini that runs a commands parser so you can set any frequency simply by sending is over the serial port. It can be run on voltages from 3,3V to 5V and takes about 140mA of current. There are two complimentary 50 ohms outputs that give out 0dBm. The output is pretty flat over the entire frequency range. It has a stability of 2.5ppm (parts per million) or better when using the built-in TCXO 10MHz reference.

Optical Spectrum Analyzer
-
an optical spectrum analyzer for analyzing short wavelengths from 350nm to 1000 nm. Because it adopts a Fourier spectrum system with a Michelson interferometer, the 8341 can measure the coherence. With its narrow wavelength resolution of 0.01nm * , the 8341 is very effective for the evaluation of not only CD/DVD laser diodes, but also for blue-violet laser diodes. In addition, the built-in He-Ne laser acts as a wavelength reference to ensure a high wavelength measurement accuracy of ±0.01nm * . Finally, with its fast 0.5s * measurement speed, the 8341 is ideal for building into systems for mass production and evaluating temperature characteristics of system components.

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%.
