![]() 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. 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. 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. 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. Updating the VIs means a lot of work, but what are the benefits? A slightly slimmer VI is none in my opinion and I cannot think of an Igor feature, that is not already supported.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. At the time I wrote the VIs I looked about the old VIs of Gary Johnson that was written for Igor 4 where Igor waves had only one dimension. There is a very good Igor xop that can read hdf5 files. I know of other people who use the hdf5 file format for this purpose. Not being able to write to an Igor binary wave continously is a limitation of this file format you have to deal with. If you insert the polymorphic VI in your program, LabView will replace it with the specific VI that is required for the data array you connected. ![]() As soon as the LV array reaches this limit, you can save it to disk and start again. Referring to your example: I think 50 MB of data is not very much. Igor binary waves are not suited for continous acquisition, because you have to know not only the length of the wave but also each value in order to calculate the checksum which is required for a valid file. Maybe using classes instead of polymorphic VIs. Any thoughts on this?Īlso, I think that the program as it is can probably stand to be updated. This would be problematic as we might run into some memory issues if we just preallocate a huge chunk of memory before hand. The one gotcha seems to be that you need to know the size of the wave before we actually write the wave. I think this is possible, but I haven't really delved into this.
