This manual uses certain conventions that you should become familiar with
before attempting service.
Throughout this manual, the term module appears. A module is composed of
electrical and mechanical assemblies, circuit cards, interconnecting cables, and a
user-accessible front panel. References to a module are different than references to
products such as “Sampling modules”, “Phase Reference modules”, or “Accessory

Instrument and Module Compensation
Performing a vertical compensation will maximize the accuracy of the automatic
measurements you take. This procedure uses internal routines to optimize the
vertical offset, gain, and linearity.
A complete compensation requires running separate compensations on the
mainframe and the modules.

d. Push the Vertical channel button for the channel you connected to in step 2.
e. Turn the Vertical SCALE knob to set the vertical scale to 20 mV/div.
The channel scale readout is displayed in the Control bar at the bottom
of the graticule.
4. Set the time base: Set the Horizontal SCALE to 1 μs/div. The horizontal
scale readout is displayed in the Control bar at the bottom of the graticule.
a. Click Setup > Display in the main menu bar. In the Disp Setup dialog
box, set the display Style to Normal and enable (check) Show Vectors.
b. Close the Setups dialog box.
c. Rotate the vertical OFFSET knob counterclockwise so that the base of
the square wave is about 2 divisions below the center graticule. This is to
ensure that a vertical trace will be seen for rise and fall.

One period of t
horizontal divisions on-screen.
Rotating th
waveform on-screen (more horizontal divisions per waveform period),
counterclockwise rotation contracts it, and returning the horizontal scale
to 1 μs/div returns the period to about five divisions. Leave the time
base set to 1 μs/div.
Rotating the horizontal POSITION knob moves the waveform left and
right on the screen.
NOTE. The signal will not move past the minimum position setting.
6. Set up the Mag1 time base:
a. Push the Horizontal View MAG1 front-panel button. The Mag1 time base
view displays below the Main time base v iew.
b. Set the Horizontal SCALE to 1 μs/div. The horizontal scale readout
is in the Control bar at the bottom of the graticule and now shows the
horizontal scale value of the Mag1 time base view.

7. Verify that the Mag1 time base operates: Confirm the following statements.
The Mag view brackets on the Main View waveform (top graticule) are a
full-screen width apart (10-divisions) as shown in the following figure.
One period of the internal clock signal (a square wave) in the Mag view
(bottom graticule) is about five horizontal divisions on-screen as shown in
the following figure. (Matches the waveform in the top graticule.)
Rotating the Horizontal SCALE knob clockwise to 500 ns/div expands
the waveform in the b ottom graticule to double the period (about 10
orizontal divisions per waveform period); rotating the Horizontal
h
SCALE knob counterclockwise returns the Horizontal scale setting to
1 μs/div returns the waveform period to about five divisions. Leave the
Horizontal Scale set to 1 μs/div.

trigger delay jitter tests, check one channel of each small-module slot.
In addition, to confirm that a main instrument can properly compensate all
channels in all modules in all main instrument slots, do the DC VoltageMeasurement Accuracy using the tested two-channel 80E00-series module.
(See page 177, DC Voltage Measurement Accuracy.) Perform this check for
each channel of each small-module slot.
Be sure to run the instrument compensation routine with the tested module
installed each time you move the module to a new slot.

Prerequisites
To check a modul
using a main instrument that has passed the process just described for checking a
main instrument as an independent product.
NOTE. Checking the main instrument and modules as independent products
verifies each product independently for all measured specifications, except for DC
voltage accuracy of the main instrument and of 80E00 modules. The procedures
do check tha
that any combination of a main instrument and electrical module that passed
testing as independent products will meet the system DC voltage accuracy
specifications.
The Brief Procedures section of this manual includes a DC accuracy check to
support verification by users that their specific combination of main instrument
and electrical module meets system specifications. This test uses the main
instrument DC Calibration Output and does not require external test generators.
The tests in this section comprise an extensive, valid confirmation of performance
and functionality when the following requirements are met:
The cabinet must be installed on the instrument.

t DC compensation is functioning properly, so it is highly probable

and the procedure Perform the Functional Tests. (Seepage2,InstrumentDiagnostics.) (See page 6, Instrument Functional Tests.)
A compensation must have been done within the recommended calibration
interval and at a temperature within ±2 °C of the present operating
temperature. (If, at the time you did the procedures Perform the Diagnostics
and Perform the Functional Tests, you also did the Perform the Compensation
procedure consider this prerequisite met). (See page 3, Instrument and
odule Compensation.)

The instrument must have been last adjusted at an ambient temperature
between +20 °C and +30 °C, must have been operating for a warm-up period
of at least 20 minutes, and must be operating at an ambient temperature.
Observe all safety rules, especially regarding voltage hazards.
These procedures cover all instrument models. Please ignore checks that do not
applytothespecific model you are testing.

The procedures mentioned in Main Instruments section use external, traceable
signal sources to directly check warranted characteristics. (See page 151,
DSA8300 Performance Verification.) The following table lists the required
equipment.
WAR N ING. So
me of the generator equipment used to complete the performance
tests may be capable of producing dangerous output levels.
Optical generators may cause eye damage. Electrical generators may produce a
shock hazard.
Always turn generators to off or 0 before connecting and disconnecting from
the test setup.
Observe all the manufacturer's safety information provided with the test
equipment.
