Section 2-7844/R7844 Operators
SPECIFICATION
INTRODUCTION
Information given i n this section of the manual applies to
both the 7844 and R7844 Dual-Beam Oscill oscopes, except
as otherwise i ndicated. The R7844 is electrically identical
to the 7844, but is adapted for mounting in a standard 1 9-
inch rack. Rackmounting Instructions and a dimensional
drawing for the R 7 844 are given i n Section 3.
Manual. The following electrical characteristics apply over
an ambient temperature range of O°C to +50°C, except as
otherwise indicated. Warmup time for given accuracy is 20
minutes.
NOTE
This instrument will meet the electrical characteristics listed
in the Performance Requirement column of Table 2-1 follow­
ing complete calibration as given i n the Service Instruction
Many of the measurement capabilities of this
instrument are determined by the choice of
p/ug�in units. The following characteristics
apply to the 7844/R 7844 Oscilloscope only,
See the System Specification in this section
(Tables 2-2 and 2-3) for specifications of the
complete system.
