INSTRUMENT OPTIONS
Option 1
Deletes Readout System and Probe Power. circuit.
Operation of the instrument is unchanged except that there
is no alphanumeric display on the CRT and active probes
must use an accessory power supply.
The Readout System and Probe Power functions can be
added at any time by ordering the Readout Conversion Kit
040-06 13-00.
Option 3
Provides Electro-Magnetic Interference (EMI!) shielding
to meet MIL-1-6181D limits for radiated interference from
150 kilohertz to 1000 megahertz, and for conducted
interference from 150 kilohertz to 25 megahertz.
Any unused plug-in compartments must also be covered
with an EMI shielded blank plug-in panel in order to meet
the EMI interference specifications. Order or use Tektronix
Part No. 016-0155-00 only. One is required for each unused
compartment. This applies whether the mainframe was
ordered as an Option 3 or modified with the appropriate
EMI! Conversion Kit.
Option 3 can be added at any time by ordering the EMI
Modification Kit 040-06 12-00.
Option 4
Replaces the standard CRT with a one-half scan CRT —
(four by five centimeter graticule area) to provide maxi-
mum trace brightness and optimum photographic writing
speed.
