1st Digital signal analyzer

[rena]

Hello, I’d like to buy my first digital Logic analyzer to work on old digital effectors you find in recording studio (eventide, lexicon…).
I have the opportunity to buy a Rigol DS1052D or a HP54645D.
Does anybody have any recommendation about those models please ?

This one has a quite reasonable price https://www.sparkfun.com/products/18627

The DS1052D is a 50 MHz scope, the HP is 100 MHz.  It may be possible to unlock the Rigol to 100 MHz, ask over in the Test Equipment forum.

Then make a spreadsheet of capabilities for comparison.  Band width (unlocked?), sample memory size, maximum sample rate and so on.

It's too bad you can't get a deal on the Rigol DS1054Z or the Siglent SDS 1104X-E as these are 4 channel scopes and quite handy for decoding things like the SPI protocol.

Thank you for your advice !
I took the HP since it was quite cheap.
I will start with it a buy something better if I feel the need.
Thanks again !

Perhaps I'm too late to the party. Probably, both will do fine for a beginner. There are a few things that I'd like to mention. Rigol has 5x the sampling rate. Also, I have doubts that 100MHz are useful at 200Msps due to aliasing. Physically, rigol is much smaller and more shallow (judging from the pics, didn't compare specs), leaving more space on the table (unless you use shelves).
