Hello,
Our firm has bought oscilloscope: "MSOX3024A Oscilloscope: 200 MHz, 4, Analog Plus 16 Digital Channels".
We perform the measurement signal to the SDRAM in hardware devices that test.
Signals period may be 0.5 ns (10 ^ (-9) second) to 20 ns (10 ^ (-9) seconds).
I have two questions about digital probes which are supplied with the oscilloscope.
1. Which is the maximum of delay from the actual values for displayed signal on the oscilloscope when measured with the digital probes?
2. Which is the maximum delay of the displayed signal relative to the actual signal from the digital probes?
Informations about digital probes are:
"Agilent 54620-61601 LOGIC ANALYZER PROBE CABLE (16 Channels)",
input Z:100 KOhm » 8pF, Max: ±40V
I would ask you if you have the documentation with the answers to these questions in electronic version (pdf, etc.) of the Agilent company that recommend it.
Thank you very much.

1. Which is the maximum of delay from the actual values for displayed signal on the oscilloscope when measured with the digital probes?
- Do you mean the delay through the cables, or the channel-to-channel skew? The delay through the cables doesn't matter, since they will all be the same. The channel-to-channel skew, according to the datasheet (available online) is 2ns (typical), 3ns (maximum).
2. Which is the maximum delay of the displayed signal relative to the actual signal from the digital probes?
- I really don't understand this question. Please draw a picture that explains what you mean.
I also saw "Signals period may be 0.5 ns (10 ^ (-9) second) to 20 ns (10 ^ (-9) seconds)."
- This scope isn't fast enough to look at these signals. The digital channels sample at 1GSa/sec (period of 1nsec), and BW of the scope is only 200MHz (as it says on the front of the scope). To look at the signals you are talking about, you need at least 2.5 GHz of BW, and a digital sampling rate of 5GSa/sec, which means a much more capable set of tools.
