Instrument Mainframe
PI-11006
The PI-11006 Instrument Chassis was designed to accommodate the power and noise requirements of some of Pulse Instruments analog instrument cards. These instrument cards, such as the PI-41401, PI-41702 and others supply signal outputs that require more current from the -12 V supply than available in a standard chassis. Therefore this chassis has a larger -12 V power supply that provides 2.5 Amps.

PXI Dual 8 to 1 RF MUX MCX 75 Ohm
40-834-102
The 40-834-102 is a 75 Ohm 8 to 1 RF MUX with 2 banks in a single PXI slot. It has been designed to exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. Each MUX has been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The design of the 40-834 minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.

Automated Tuners / Impedance Tuners / Load Pull Tuners
MT97x, MT98x and XT98x series automated tuners (also known as automated impedance tuners and automated load pull tuners) are precision instruments that are optimized for a broad class of in-fixture and on-wafer applications, and may be used in any automated or manual application requiring the ability to match the impedance of a microwave circuit element or to establish specific impedances at a terminal interface. The tuner design is based on the slide screw concept using the inherently broadband slab-line transmission structure. Each unit has two non-contacting probes deliver high VSWR with superb accuracy and reliability over a wide frequency range. These probes can be fully retracted leaving a low-loss, well-matched transmission line, which is a significant benefit in power related applications where two-port tuners capable of handling large amounts of power are required. As integral components of Maury Device Characterization Solutions, these PC-based tuners are controlled using Maury's family of Device Characterization Software tools, including MT930 IVCAD, MT993 ATS and the DLL-based measurement automation environment. Maury Microwave automed impedance tuners are ideal for load pull, harmonic load pull, active load pull, hybrid active load pull, noise figure, noise parameters and all automated tuner applications.

Basic Quad J-Type Analog Thermocouple Amplifier
SEN-30103-J0
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.
