Hantek6074BC-hack to 250MHz
« on: March 13, 2016, 03:26:54 PM »


 I Have bought a Hantek6074BC 70 MHz BW.Can I hack it to Hantek6254BC 2500 MHz BW? :box:

Someone can help me?

Hello Stevie,

Someone recommended it to me.
Now you have one, what do you think about this 6074BC accuracy of measurements?

Hi there,

any news on speeding up the 6074BC? I am interested in doing so, too. :)

Thanks,
NewtoM

Hi,

my Hantek PC 6074BC just arrived and I decided to take a look inside. See attached pictures.
With a 200MHz bandwidth hack in mind, I was trying to connect via serial interface, but had no luck.

I tried JP1, which seems like a serial connector, but there is no signal. Maybe the U31 IC is missing. (At U31, the shorted pins 25 and 26 remind me of an FTDI USB to serial interface chip, but the other pins do not seem to match with the pinout of the FTDI FT232.)

The other serial-like connector on the south of the front-side is also no serial connector (same signal on 4 pins).

Any comments or ideas are welcome.

Get the symbol of marked uC and search for datasheet, find uart pins on pinout and try them. :)

Hi kaczy9999,

thanks for the idea. Here's the pinout for the ┬ÁC: http://www.cypress.com/file/138911/download#page=21.
Unfortunately, it has no UART pins. :(

What it has are SPI (or probably, TWI) pins, which are connected to another 8-pin IC (tagged U807) on the other side, which has its label scratched off.... Great.

In the meantime I am pretty sure that the 8-pin IC is an EEPROM chip, which holds the firmware (max. 16 KB) for the microcontroller (see USB Boot Methods at http://www.cypress.com/file/138911/download#page=6 and I2C Controller at http://www.cypress.com/file/138911/download#page=15).

Now, even if I'd find a way to change contents of the EEPROM, it would be a shot in the dark to change it so that the bandwidth changes. I am not even sure that the relevant parameter is in there.

Any ideas?
NewtoM

Hi Mr Gyro had directed me here I also have Hantek 6074BE scope It has lots of problems Which are described here https://www.eevblog.com/forum/testgear/please-help-my-oscilloscope-trigger/

I invite anyone with Hantek pc scope to Visit my thread ...

Thanks..
