Start Up
Before you use the digitizing oscilloscope, ensure that it is properly installed
and powered on.
To ensure maximum accuracy for your most critical measurements, you
should know about signal path compensation.
Signal Path Compensation
Be sure you compensate your oscilloscope for the surrounding temperature.
This action, called
Signal Path Compensation (SPC) , ensures maximum
possible accuracy for your most critical measurements. See
Signal Path
Compensation
on page 3-138 for a description of and operating information
on this feature.
To properly install and power on the digitizing oscilloscope, do the following:
Installation
1. Be sure you have the appropriate operating environment. Specifications
for temperature, relative humidity, altitude, vibrations, and emissions are
included in the
TDS 520A, 524A, 540A, & 544A Performance Verification
manual (Tektronix part number 070–8712–01).
2. Leave space for cooling. Do this by verifying that the air intake and ex-
haust holes on the sides of the cabinet (where the fan operates) are free
of any airflow obstructions. Leave at least 5.1 cm (2 inches) free on each
side.
To avoid electrical shock, be sure that the power cord is discon-
nected before checking the fuse.
3. Check the fuse to be sure it is the proper type and rating (see Figure 1-1).
You can use either of two fuses. Each fuse requires its own cap (see
Table 1-1). The digitizing oscilloscope is shipped with the UL approved
fuse installed.
