Specifications
These specifications apply to all TDS2000C series oscilloscopes. To verify that an
oscilloscope meets specifications, it must first meet the following conditions:
The oscilloscope must have been operating continuously for twenty minutes
within the specified ope rating 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 the l
ast time the Do Self Cal operation was performed.
The oscilloscope must be within 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 w ith the symbol
are chec
kedinthechapterPerformance Verification.(Seepage4-1,Performance
Verification.)
Signal Acquisition System 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.

Maximum Input Voltage
Based on sinusoidal or DC input signal. The maximum viewable signal while DC coupled is ±50 V offset
±5 V/div at 4 divisions, or 70 V. AC coupling allows measuring signals on a DC level up to 300 V. For
nonsinusoidal waveforms, peak value m ust be less than 450 V. Excursions above 300 V should be less
than 100 ms in duration, and the duty factor is limited to < 44%. The RMS signal level must be limited to
300 V. If these values are exceeded, damage to the instrument may result.

Displayed vertically with 25 digitization levels per division, 10 divisions dynamic range.
2 mV/div setting is generated by digital multiplication and the resolution is reduced. Given 100 levels
available, the resolution is >6.5 bits.
