Typical Characteristics
This subsection contains tables that list the various typical characteristics
that describe the TAS 455 and TAS 465 Analog Oscilloscopes.
Typical characteristics are described in terms of typical or average
performance. Typical characteristics are not warranted.
This subsection lists only typical characteristics. A list of warranted characĆ
teristics starts on page 1Ć9.

20ĂMHz.
Trace Shift Leakage The typical amount of trace shift while changing the input coupling
between GND and 1 MW DC is as follows:
Condition Typical Trace Shift
-10_ Cto+35_C <0.5 mV.
+35_ Cto+55_C <2 mV.
Variable Volts/Div Offset 0.5 division trace shift while changing the variable volts/div setting.
Chop Mode Clock Rate >500 kHz, <1 MHz.
Chop mode is allowed from 0.5 s to 10 ms sec/div settings.
Noise (measured tangentially) H v0.06 div at w10 mV/div (600 mV).
H v0.10 div at 5 mV/div (500 mV).
H v0.14 div at 2 mV/div (280 mV).
