Specifications
These specifications apply to all TBS1000 series oscilloscopes. To verify that an
oscilloscope m eets specifications, it m ust first meet the following conditions:
The oscilloscope must have been operating continuously for twenty minutes
within the specified operating temperature.
You must perform the Do Self Cal operation, accessible through the Utility
menu, if the operating temperature has changed by more than 5 °C (9 °F)
since th e l
ast time the Do Self Cal operation was performed.
The o scilloscope must be w ithin the factory calibration interval of one year.
Specifications are provided in the following tables. All specifications are
guaranteed unless noted "typical." Specifications that are marked with the symbol
are chec
ked in the Performance Verification section. (See page 4-1, Performance
Verification.)
Signal Acquisition S ystem Characteristics
NOTE. All amplitude-related or modified specifications require 1X probe
attenuation factors unless otherwise specified. This is due to the way the displayed
sens
itivity works. This does not affect actual methods of attachment. It only alters
the relationship between displayed scale factors and the specifications.
