CAT-5 Video Variable Filters
-
It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.

Clean Air Curtain
CAC
-
Clean Air Curtain (CAC) is a compact tabletop air filter device. It creates an invisible air barrier between two persons to prevent transmission of viruses like Covid-19. Conventional air filters focus only on the quantity of air filtered per hour. However, the high-speed clean air jet of CAC ensures that filtered air also mixes well within the room. Since short-cycling is eliminated, CAC offers a much bigger coverage area. CAC is especially useful for personnel working on shop counters & receptions.

Firmware for High-speed HDLC Mode
OP-FW10
-
OP-FW10 is firmware to upgrade protocol analyzer LE-7200/LE-3200 to dedicated analyzer that is specialized for High-speed HDLC communication up to 10Mbps. By installing this OP-FW10 to LE-7200/LE-3200, HDLC measurement processing such as the trigger and filter that were processed by software of the analyzer can be replaced to the hardware processing by FPGA built in the analyzer. Therefore, a maximum speed of HDLC supported is vastly improved. After installation of OP-FW10, You can switch to the usual firmware that supports multi protocol by pressing “SHIFT” and “0” keys at the same time when turning on the power of the analyzer. Therefore, it saves you trouble to reinstall firmware.
