Rise time, typical
Model Expected full bandwidth rise time
TBS1202C 2.5 ns
TBS1102C 4 ns
TBS1072C 5.5 ns
TBS1052C 8.4 ns
Rise time is generally calculated from the following formula: Rise time in ns = 420 /
Bandwidth in MHz
√ Vertical position accuracy,
offset accuracy
This is the accuracy of the nominal voltage level represented by the code at the
vendor of the A-D converter's dynamic range.
± (0.01 X |offset – position | + DC Balance)
Vertical position ranges ± 5 divisions
Common Mode Rejection Ratio
(CMRR), typical
With the same signal applied to each channel, CMRR is the ratio of the acquired
signal amplitude to the amplitude of the MATH difference waveform, either (Channel
1 - Channel 2), (Channel 2 - Channel 1)

100:1 at 60 Hz, reducing to 10:1 with 50
MHz sine wave, with equal Volts/Div and
Coupling settings on each channel.
Crosstalk (Channel Isolation) Section 4.11.1 of IEEE std. 1057. It is the ratio of the level of a signal input into one
channel to that of the same signal present in another channel due to stray coupling.
Model Common Mode Rejection Ratio
TBS1202C (200 MHz models) >100:1 with 200 MHz sine wave and
with equal V/div settings on each
channel.
TBS1102C (100 MHz models) >100:1 with 100 MHz sine wave and
with equal V/div settings on each
channel.
TBS1072C (70 MHz models) >100:1 with 70 MHz sine wave and with
equal V/div settings on each channel.
TBS1052C (50 MHz models) >100:1 with 50 MHz sine wave and with
equal V/div settings on each channel.
