3206 Bandwidth - 200 MHz????

Postby br1970 » Fri Oct 12, 2007 8:41 pm

I just had a PicoScope 3206 sent thru our in house metrology department and the resulting bandwidth is around 10 MHz. The test criteria is send a 1.2 Vpp sinewave to the input and find the 3 dB cut off point. I then followed up with my own test at my bench using an Agilent 33220A Function Generator and obtained the following data:

Frequency (MHz) Input (Vpp) Output (Vpp) Db
0.5 1.2 1.198 -0.01448856
1 1.2 1.183 -0.123930028
5 1.2 1.04 -1.242958135
10 1.2 0.8 -3.521825181
20 1.2 0.515 -7.34748034

How do you claim this is a 200 MHz bandwidth scope with these results? Only Channel A was active during these measurements.

Thanks

Found issue

I found the issue after reading the 250 MHz probe specs on your site. I had the probe set to 1:1 which as it states is limited to 10 MHz. Thanks for a great product.
