@clifford: --- Quote from: clifford on December 28, 2013, 06:35:04 pm ---Wow! The Agilent AppNote is a good read. Thanks! (Nothing really new but everything in one place.) :-+ ... --- End quote --- The first pages [1-5] have reminded me those days studying signals and systems. Figure 4 is a point of view very graphic about the aliasing. Pages 6, 8 and 9 are interesting, too. I wonder if the DS2000 have the FIR filter implemented in the DSP, or in the FPGA. Thanks. ;) @Teneyes: Teneyes and its magic. Lovely sinc... A few days ago someone mention something about a Tek oscilloscope that in dots mode showed more samples than should be. It's not magic, are interpolated (maths). |

Wasn't it that, originally, the DS1074Z hacks didn't add 100MHz option? Is that a new addition? |

neamyalo thank you for your work - would you be willing to upgrade to the latest firmware and repeat the full dump? Your dump says it is 00.02.00.00.04 and the latest fw I know of is 00.02.01.00.03. Thanks! |

The 100 MHz option is a relatively new addition posted by seronday on 12 December 2013: https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg346786/?topicseen#msg346786 --- Quote from: seronday on December 13, 2013, 12:11:50 am --- --- Quote from: seronday on December 12, 2013, 01:36:11 pm ---Anyone who wants to change their new DS1074Z into a DS1104Z use the following Codes:- DSHA makes a DS1104Z with no options enabled . DSHR makes a DS1104Z with all options enabled . The 3dB bandwidth for the DS1104Z is approx 160Mhz. The 3dB bandwidth for the DS1074Z is approx 90Mhz. --- End quote --- Minor correction to my previous post after some further investigation. DSHA also enables the 500uV setting and another unknown, (at present), option. DSEA is the correct code to change to a DS1104Z only. ( no options ). See table below. Code DS1104z Unknown 500uV setting DSBA X DSCA X DSDA X X DSEA X DSFA X X DSGA X X DSHA X X X So to change a DS1074Z into a DS1104Z with all options enabled except the 500uV/div (which does not work correctly at present), the code will be DSER. It is possible to revert back to original, by using the SCPI command " :SYSTem:OPTion:UNINSTall " . As mentioned in my previous post, the measured 3dB down bandwidth after changing to a DS1104Z, is approx 160Mhz. All the tests were done on a DS1074Z with Ver:00.02.00.SP1. --- End quote --- |
