which would mean that the data is actually full of holes. ie grab 40k bytes, transfer it to the PC, store it on hdd, get the next 40k. Another person noted that the record function works. A quick calculation on USB2 transfer rates suggests that the device goes blind whilst it transfers the next 40k bytes of samples.

And the faster the sample rate, the less likely the trigger is to happen. Like one of the other folk here, I brought this thing to record single shot events, but triggering is almost non existent. Somebody mentioned an API to the device, where can I find that please.

I have not traced the circuit to see whether it plays any major part in analogue acquisition However I note that the (awful) software is the same for both scopes, so I am guessing the protocol to the cy 7C68013 is the same. The altera gives a lot of extra I/O pins for logic analyser / sig.gen.

I have the DDS140 (BM104) which uses ad9288 cy7C68013 altera max II.

' should be shown next do Device - press Lg EEPROM 'DnLoad to 64k EEPROM' - select 'All files *.*' - select 'DDS120_24LC64.bin' - wait for finish then reconnect scope - wait for scope driver to finish installation - DoneĪ little off topic.

When doing so, it is important to select the '64k eeprom': - disconnect (open) jumper R32 from pcb - connect scope to PC - wait for USB recognition (CYPRESS default VID/PID) - connect (close) jumper R32 on pcb - start Cypress USB Console - start EZ-USB Interface (Options -> EZ-USB) - 'Cypress EZ-USB. (Should also be possible via a CH341A eeprom programmer, but haven't any success) Reprogramming can also be done via the CYPRESS USB Control Center (see attachment). 'DDS120_24LC64.bin' - write device (button), verifies when finished - reconnect scope, wait for scope driver to finish installation O0 Flashing is done via a simple parallel-port-programmer called 'Easy I☬ Bus interface': Bottom of page. ED2: Updates.īIG thanks to ganzuul and franky, we are back in business! Reflash the EEPROM in short: - disconnect (open) jumper R32 from pcb - connect scope to PC - wait for USB recognition (CYPRESS default VID/PID) - connect (close) jumper R32 on pcb - start Ponyprog2000 - set EEPROM type to 2464/2465 - I2C bus 16bit eeprom - do a calibration (Setup -> Calibration - read device to backup state (button) - File -> Open Device File -> i.e. R4 - AD9288BSTZ-40: C10 - CY7C68013A: R13 - 24LC64: I'll bump this when I know more about this thing! ED: Added some high-res pics to my private web server: These photographs are just under 6MB each. I ordered it from here: So far I'm happy with the hardware I actually got for the money but will have to look into making the scope work with some existing open source package. I placed my order on May 8th, so it took 12 days to deliver it from China to Finland. There is also an API to the driver with a sample project for the Microsoft platform SDK. There's a rather exposed I2C interface, which I have heard lends itself to hackability. They are probably not true 100MHz probes, but one review of them that I saw referred to them as 'good stuff'. The two probes are of the model TP6100, which when sold separately reportedly cost $9 on eBay. The lowered sampling rate appears to be a way to avoid writing sub-pixel graphing accuracy, but it could also be a self-imposed CPU load ceiling. The resulting graph is not as pretty as I'd like. The supplied software switches down to a sampling rate of 2.4 'MHz' when over a certain time division, and then over the time division it switches up to 50MHz.

ED: We have FOSS code!! /ED This scope is advertised as 50Ms/s while the ADC runs at 40MHz.
