The newly introduced Lake Shore PS-100 is a pre-configured solution for customers needing a basic, low-cost cryogenic probe station. This packaged system consists of a TTPX probe station set up for four-point triaxial probing, ideal for sensitive, high-impedance DC measurements.
The PS-100 is intended to offer a straightforward cryogenic probing solution without the complexity of choosing from multiple configuration options. The four arm triaxial scheme is the most commonly requested probe station configuration and serves many different applications.
By pre-configuring these units, Lake Shore can take advantage of operational efficiency in manufacturing to offer a very competitive price and a lead time of just 3-4 weeks.
The PS-100 has the same performance specifications as the existing TTPX and can be upgraded with standard TTPX options in the field.
- Programmable current output, 100 nA to 100 mA
- Current reversal feature
- 7 decades of low-noise output current, selectable in 13 steps
Lake Shore’s new Model 121 programmable DC current source is a CE-marked precision instrument suitable for bench-top use or panel-mounted operation in labs, test facilities, and manufacturing environments.
The Model 121 provides a low-noise, highly stable source of current up to 100 mA, with convenient manual selection through 13 pre-set output levels, each representing a ten-fold change in power when attached to a resistive load. A “user” setting allows the current output to be defined anywhere within the operating range of the unit, from 100 nA to 100 mA.
Programmable operation is also possible via the instrument’s USB computer interface, through which the Model 121 can be commanded to output any desired current at any time. Thus, application-specific test currents can be driven from an external PC.
