2.92mm to ProLink Adapter with Probe Power and Communication Pass Through
L2.92A-PLINK
The Teledyne LeCroy LabMaster 10 Zi oscilloscope utilizes precision 2.92mm input connectors to achieve up to 36GHz of input bandwidth. But some applications may require the use of lower-bandwidth probes for performance and cost reasons.The L2.92A-PLINK adapter converts the 2.92mm interface to a ProLink interface. This brings the benefits of a wider selection of probes to the LabMaster 10 Zi such as Dx10/Dx20/Dx00A-AT 4-6 GHz differential probes and DH Series 8 to 20 GHz differential probes using the ProLink oscilloscope probe connection. Full probe power and control is provided through a built-in LEMO interface.

2-Port Optical Tunable Filter
Optoplex's Tunable Optical Filter, also known as Optical Tunable Filter or Tunable Bandpass Filter, is an integrated module, consisting of micro optics and electronics. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). The selected channel can be varied (tuned) within the operating wavelength (frequency) range by a remote command sent through the built-in control PCB and firmware.

Low Voltage Test & Measurement
Low voltage testing is able to catch errors such as shorts and opens by applying current to a wire and measuring the voltage. The wire will have a current affected by several factors including resistance and components. If the wire is connected correctly, the test will read low resistance. That means current is flowing through the wire as expected and reaching the required connections. If the tester reads high resistance it means something is impeding the current from reaching its destination. This could be caused by a number of causes.

Low Noise Pre-Amplifiers
Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.
