nDelay between channels
CSA7404, CSA7154, TDS7404,
TDS7254, TDS7154,
TDS6604, & TDS6404
≤30 ps between any two channels with the same scale and coupling settings
TDS7104 & TDS7054 ≤50 ps between any two channels with the same scale and coupling settings
nChannel-to-channel crosstalk
CSA7404, CSA7154, TDS7404,
TDS7254, & TDS7154
≥15:1 at rated bandwidth (CSA7404, TDS7404 & TDS7254 only), and
≥80:1 at ≤1.5 GHz or the rated bandwidth, whichever is less.
Assumes two channels with the same scale settings
TDS7104 & TDS7054 ≥100:1 at 100 MHz, and ≥30:1 at the rated bandwidth for any two channels with
the same scale and coupling settings
TDS6604 & TDS6404 ≥20:1 at rated bandwidth, and ≥80:1 at ≤1.5 GHz or the rated bandwidth,
whichever is less. Assumes two channels with the same scale settings
1Rise time is calculated from the following formula:
RiseTime =.40
BW where BW is the 3 dB bandwidth in Hz and RiseTime is in seconds.
