I really lament the loss of rs232 serial ports and also parallel ports from modern computers.  Those were great reliable interfaces when you just needed to get the job done quick and dirty.  Now you have to go all USB, and nothing is quick and easy anymore :(

Oh yes, the loss of the Serial port...

I have 5 PC's here, 2 have serial ports, all have windows 7. Not one of them with hyper terminal. One dual boots to XP, but that does not have serial, so i tried a USB - Serial dongle, no luck there, then the main PC but i had fried the serial port on that only a few weeks ago. So i had to install a PCI serial card in that, and download Hyper terminal. Still that didn't work. Eventually i found my sons PC had a Serial port, i downloaded Hyper Terminal to that and finally got a connection to the Scope. Once i had got that far, it was easy, but just getting a PC with a working serial port to talk to the scope took an age.

 It was only later after i had already done the scope did i think of downloading an alternative terminal program to stop all that Alt 010 business. So i searched found one and thought id share.

Am I right in connecting each pin in the plug to the same numbered pin of the other plug ? I'd rather reconnect them all to save having wires floating around, I may also be using this at work so need it to look like its not that crazy

For the simple case of PC serial port -> scope, yes.  2,3,4 straight through to 2,3,4.  frolic's link provides a pretty solid diagram.

Well I did it ! I'm so pleased.

now I'm getting quite enthusiastic about this thing where you can control the scope via a pc, is there any way of making use of this to setup the whole scope to the defaults you want ? say some sort of batch file ? I suppose there is also the possibility of having a uC control the scope.

KTP:
by did it, do you mean you also did the 1052 to 1102 conversion?

If you look at the files on the disk that came with your scope there is a document that gives example code for controlling your scope from a visual basic or visual c program (although maybe over usb, i can't remember and don't have the file in front of me).

yes I did the conversion,

I have also been able to nail the scope down on the inherent noise it suffers from (fine use of the trig knob) I would guess it is sinusoidal as it is quite weak and i estimate the frequency (its so small an amplitude the scope can't actually do any measuring functions in respect of time) to be 100 MHz: the speed of each of the 10 ADC's

EDIT: the duration of each waveform of noise is 10 nS that does work out to be 100 MHz dosen't it ?
