The dPatch amplifier system, in combination with SutterPatch software, has been engineered to automatically capture and store all amplifier settings, stimulus information and external experiment parameters, and associate them in time with the raw data traces. All I/O channels are sampled continuously (200 kHz for analog inputs, 250 kHz for analog and digital outputs) and available through the user interface. Using a multiplexer-free design, the dPatch provides 8 fully differential analog input channels, 4 analog output channels, and 16 digital outputs (TTL). In addition, the limited life expectancy of Peltier elements causes reliability concerns that we found unacceptable.īUILT-IN DATA ACQUISITION SYSTEM MEANS NO THIRD-PARTY COMPUTER INTERFACE In the two resistive feedback modes, the dPatch amplifier is even quieter than any of the competitor systems. One of the development goals of the dPatch headstage was achieving a comparable noise performance at room temperature, without the need for a cooled headstage. As a company that makes micromanipulators, we are highly sensitive to the performance of the system within a complete electrophysiology rig.Īctive cooling can help get a slightly better noise specification on paper, but in the real world the disadvantages far outweigh the slight gain in specsmanship. ![]() This is THE MOST COMMON source of what users perceive as "manipulator drift". ![]() The heat generated causes thermal drift which makes it almost impossible to stay patched while doing single-channel work. Active cooling in amplifier headstages use Peltier cells, which cool the electronics for slightly better performance, but generate considerable heat on the opposite side of the cell. At a bandwidth setting of 1 kHz, the dPatch system provides a signal resolution of better than 22 bits.Īctive cooling causes numerous problems that actually create more "noise" in the long run. For lower filter settings, automatic downsampling increases resolution while optimizing data rates. A resolution of 18 bits is achieved at 1 MHz. Output filtering has thirteen settings between 100 Hz and 1 MHz. Each headstage is continually sampled at 5 MHz. One unique feature with dPatch is the headstage data sampling system. #Igor pro 8 no data was found in file free#All of our products are built in the USA, and we offer free support should you need any help.ĥ MHz SAMPLING RATE, UP TO 22-BIT RESOLUTION ![]() While other amplifiers on the market haven't been updated in 20 years, the dPatch will continue to be developed and supported WELL into the future. Sutter has a long history of standing by our products and continually improving them. The two headstages are independently configurable for either voltage clamp or FastFollower™ current clamp. #Igor pro 8 no data was found in file software#The included SutterPatch® Software facilitates data acquisition, mangement and analysis with an intuitive and easy to learn interface.Īvailable in either a single- or dual-headstage configuration, the dPatch amplifier system’s architecture makes swapping headstages, or adding a second one to a single-headstage unit, a plug-and-play operation. The processing power of this design FINALLY enables fully integrated dynamic clamp, as well as digital capacitance and resistance compensation. The dPatch amplifier system's digital architecture uses state-of-the-art methods in signal processing, such as field-programmable gate arrays (FPGAs) and Arm Core processors – technologies unavailable when the leading amplifiers in the market were designed well over 20 years ago. #Igor pro 8 no data was found in file how to#The resulting design represents a complete rethinking of how to best reduce noise and preserve signal to get the cleanest recordings possible, at a bandwidth that far exceeds anything else on the market. We asked them to design the best amplifier system possible, using the very latest in digital architecture, and pair it with a contemporary, easy-to-use, yet powerful software platform. #Igor pro 8 no data was found in file Patch#The Multi-Peak Fitting package uses the Peak AutoFind.ipf procedure, which uses the FindLevel operation to search smoothed derivatives of the data.The dPatch® amplifier system was built around a simple idea: What if we built a clean-sheet design that used the latest technology to make the next generation of patch clamp amplifiers? We hired the best hardware and software designers available in the industry, the same engineers who created the leading amplifiers already in the market.
