Specification; Electrical Characteristics - Tektronix 7B92A Instruction Manual

SPECIFICATION
This instrument will meet the electrical characteristics listed under Performance Requirement in Table 1-1, following com-
plete calibration . The following electrical characteristics apply over an ambient temperature range of OOC to +500C, except
as otherwise indicated. Warmup time for given accuracy is 20 minutes.
TABLE 1-1
Electrical Characteristics
'
Will not trigger on the sine waves of 8 div amplitude or less (internal), or 3 V or less (external) at 60 Hz or below.
Section 1-7B92A Operators
z For Internal Triggering only, the specified -3 dB frequency of the Vertical System replaces any frequencies in the above table when the num-
ber in the table is greater than the -3 dB frequency of the Vertical System .
s Triggering signal amplitude requirements increased by factor of 10 for EXT _ 10 operation.
