The Throwing Star LAN Tap Pro is a passive Ethernet tap, requiring no power for operation. There are active methods of tapping Ethernet connections (e.g., a mirror port on a switch), but none can beat passive taps for portability. To the target network, the Throwing Star LAN Tap looks just like a section of cable, but the wires in the cable extend to the monitoring ports in addition to connecting one target port to the other.The monitoring ports (J3 and J4) are receive-only; they connect to the receive data lines on the monitoring station but do not connect to the station’s transmit lines. This makes it impossible for the monitoring station to accidentally transmit data packets onto the target network.The Throwing Star LAN Tap Pro is designed to monitor 10BASET and 100BASETX networks. It is not possible for an unpowered tap to perform monitoring of 1000BASET (Gigabit Ethernet) networks, so the Throwing Star LAN Tap intentionally degrades the quality of 1000BASET target networks, forcing them to negotiate a lower speed (typically 100BASETX) that can be passively monitored. This is the purpose of the two capacitors (C1 and C2).Like all passive LAN Taps, the Throwing Star LAN Tap Pro degrades signal quality to some extent. Except as described above for Gigabit networks, this rarely causes problems on the target network. In situations where very long cables are in use, the signal degradation could reduce network performance. It is a good practice to use cables that are not any longer than necessary.DownloadsOpen source design files

The Peak Atlas ESR70 Gold is an enhanced version of the previous Peak Atlas ESR70 Plus. It does everything that the ESR70 Plus did but better.
It now measures capacitance up to 10x faster, and over a wider range, thanks to new test algorithms. The capacitance measurement is also much less influenced by parallel resistances or leakage current thanks to our new Triple-Slope measurement system.
Using the supplied gold plated probes (removable), the Atlas ESR70 Gold can measure ESR down to a resolution of 0.01 ohms, up to 40 ohms. It can even measure ESR for capacitors that are in-circuit. Probes are removable, allowing 2 mm compatible probes to be fitted. Audible alerts are produced for various ESR levels allowing you to perform many tests in succession without having to look at the display. The ESR70 automatically takes capacitive reactance into account, so even low value capacitors (down to 0.3 uF) can have the ESR measured accurately.
Features
Uses a single AAA Alkaline cell (included).
Alphanumeric LCD with backlight.
Automatic analysis-start when you apply the probes.
Automatic capacitor discharge using controlled discharge function.

The QA403 is QuantAsylum's fourth-generation audio analyzer. The QA403 extends the functionality of the QA402 with improved noise and distortion performance, in addition to a flatter response at band edges. The compact size of the QA403 means you can take it just about anywhere. Features 24-bit ADC/DAC Up to 192 kSPS Fully isolated from PC Differential Input/Output USB powered Built-in Attenuator Fast Bootup and Driverless The QA403 is a driverless USB device, meaning it’s ready as soon as you plug it in. The software is free and it is quick and easy to move the hardware from one machine to the next. So, if you need to head to the factory to troubleshoot a problem or take the QA403 home for a work-from-home day, you can do it without hassle. No-Cal Design The QA403 comes with a factory calibration in its flash memory, ensuring consistent unit-to-unit performance. On your manufacturing line you can install another QA403 and be confident what you read on one unit will be very similar to the next unit. It is not expected that re-calibration will be required at regular intervals. Measurements Making basic measurements is quick and easy. In a few clicks you will understand the frequency response, THD(+N), gain, SNR and more of your device-under test. Dynamic Range The QA403 offers 8 gain ranges on the input (0 to +42 dBV in 6 steps), and 4 gain ranges on the output (-12 to +18 dBV in 10 dB steps). This ensures consistent performance over very wide ranges of input and output levels. The maximum AC input to the QA403 is +32 dBV = 40 Vrms. The maximum DC is ±40 V, and the maximum ACPEAK + DC = ±56 V. Easy Programmability The QA403 supports a REST interface, making it easy to automate measurements in just about any language you might anticipate. From Python to C++ to Visual Basic—if you know how to load a web page in your favorite language, you can control the QA403 remotely. Measurements are fast and responsive, usually with dozens of commands being processed per second. Isolated and USB Powered The QA403 is isolated from the PC, meaning you are measuring your DUT and not chasing some phantom ground loop. The QA403 is USB powered, like nearly all our instruments. If you are setting up remotely, throw a powered hub in your bag and your entire test setup can be running with a minimum of cables. Goodbye Soundcard, Hello QA403 Tired of trying to make a soundcard work? The calibration nightmare? The lack of gain stages? The limited drive? Are you tired of dealing with the fixed input ranges? The worry that you might destroy it with too much DC or AC? Tired of the ground loops? That’s why QuantAsylum built the QA403.
