SparkFun Coulomb Counter Breakout
LTC4150
-
Odometers are extremely useful for cars, they tell you how far you have gone, wouldn't it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defined as, to put it simply, one amp for one second. This breakout is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used. When used effectively and if you start with a full battery, you’ll always know exactly how much of it is left!

Redundant Frequency and Timing Systems
-
A unique feature of our frequency standards and distribution amplifiers is that the two separate parts of the redundant system are identical and can easily be inter-changed, for maintenance purposes. What we mean by this is that that we don't have a "Master" unit and a "Slave" unit. Whatever unit is powered up first becomes the master unit and the other becomes the slave unit.

VDI Millimeter-Wave Frequency Extension Modules for PXA, MXA, EXA Signal Analyzers
-
These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.
