PXI Single 18 Channel MUX, BNC Connectors
40-735-902-S3
The 40-735 data communications multiplexer is designed for switching the data lines of serial interfaces (RS232, USB). Careful attention to the design of the module ensures that the switching system minimizes its impact on the transmission distance of USB1.1 interfaces. The MUX is available in 36:1 or 18:1 formats and enables a single source of serial data to be switched to one of 36 or 18 devices under test. This allows the data source to load information to, or receive information from, the device under test. The 36:1 version can be software configured into two independent 18 way MUXs enabling two separate sources of serial data to be connected to separate banks of 18 devices. The module is ideal for performing bulk testing of any device that relies on a serial data communications port to load software or control the device operation. It can also be used for a variety of other applications where ever a 2-pole low power MUX is required.

Dual (Bi) Directional Couplers
Pasternack dual directional coupler (also known as bi-directional coupler) series are passive devices that couple part of the transmission power in a transmission line. Our dual directional coupler components provide the bandwidth, high directivity and higher power that designers need for their most demanding applications. RF dual directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack bi-directional coupler items are RoHS and REACH compliant. Couplers that are dual directional from Pasternack are available with SC, SMA and Type N connectors. This dual/bi directional series is offered in 10dB, 20dB, 30dB, 40dB and 50dB coupling values. Power ratings for our dual directional couplers range from 10 Watts to 10 Watts. Frequency ratings for our bi-directional couplers range from 1 GHz to 8 GHz. Like the other over 40,000 RF, microwave and millimeter wave components from Pasternack, our dual (bi) directional coupler series is in-stock. Not only our these couplers in stock, they also will ship the same-day as they are purchased.

Test Fixture, Shielding Effectiveness
EM-2108 | 1.5 GHz – 10 GHz
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. 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.

Resistors
A passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

Transmission Line Probes
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 1kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.
