This may be a dumb question but I have searched the forum and net and can't seem to find an answer so here goes. I'm a scope newb and know that your probes should have a higher bandwidth than what you are trying to measure but if you have a two channel scope does it make a big difference if your probes are different bandwidth?
The scenario is I have a Fluke 106C 100Mhz scopemeter and one of the VPS210 200MHz probes is dead (it's open circuit, I'm happy to try and take it apart for the forums enjoyment if you want)
Fluke accessories are "rather expensive" in Oz and a VPS210-G 200MHz probe is $399 ex GST from RS components but the probe for a 190 Series II Scopemeter VPS410-G which is a 300MHz probe with higher CAT ratings is only $293 ex GST. I then did a bit of searching for other isolated probes and worked out the Fluke Probes are about 99.999% to really be Multi Contact Isoprobe III series and I can buy a 300MHz or 500MHz probe from RS for around the $150 mark, which seems like the way to go.
At the moment the signals I am measure are in the range of 10kHz with a 10V peak to peak so all of these probes are way more than I need but if I use a 200MHz probe in one channel and a 300 or 500 MHz probe in the other channel is it going to make a huge difference? I would rather not have to buy two new probes if I only need to buy one.
