The Analog Bandwidth when the instrument is DC coupled. V/div values are accurate for probe attenuation settings of 1X. No
probe shoul
d be installed for t hese measurements.
TBS1154, TBS1152, TBS1104, and TBS1102: DC to ≥75 MHz for 5 mV/div through 5 V/div settings with bandwidth limit at full.
Setting less than 5 mV/div are limited to 20 MHz bandwidth.
TBS1064, T
BS1062: DC to ≥50 MHz for 5 mV/div through 5 V/div settings with bandwidth limit at full. Settings less than 5 mV/div are
limited to 20 MHz bandwidth.
TBS1042: DC to ≥30 MHz for 5 mV/div through 5 V/div settings with bandwidth limit at full. Setting less than 5 mV/div are limited to
20 MHz ban

Rise Ti
me, typical
Rise time is generally calculated from the following formula: Rise time in ns = 350 / Bandwidth in MHz
TBS1154, TBS1152: The expected full bandwidth rise time: 2.6 ns.
TBS110
4, TBS1102: The expected full bandwidth rise time: 3.5 ns.
TBS1064, TBS1062: The expected full bandwidth rise time: 6.0 ns.
TBS1042: The expected full bandwidth rise time: 8.8 ns.
TBS10
22: The expected full bandwidth rise time: 14.0 ns.
