Theory of Operation
This section provides a basic description of the Real-Time Signal Analyzer
(RTSA) operation. A block diagram of the instrument is shown in this section.
(See Figure 2
General
A processor system controls the RSA6100B instrument. The instrument features
an XGA resolution flat-panel display, a transparent touch-screen, and a front-panel
with direct access to commonly used RTSA features. You can also use the RTSA
with a mouse or other pointing device, and/or a keyboard.
The RTSA uses the Microsoft Windows 7 operating system.
Signal Path and Processing

RF Signal Path
Acquisition System
Processor System
An RF signal enters the RTSA through a direct coaxial connection (N-type for the
RSA6106B and RSA6114B, 3.5 mm for the RSA6120B) to the input connector.
The RF signal path conditions the input signals and passes them to the acquisition
system for sampling and processing. The RF signal path consists of three
frequency conversion stages, band-limiting filters, and signal level adjustment
stages. The purpose of t
portion of the input signal range to a intermediate frequency (IF) where it can be
sampled by a high dynamic range A/D.
Control of the RF signal path is performed by the processor system.
The acquisition system samples the IF signal and converts it to digital signals.
These digital signals are then filtered numerically and processed either for direct
display or by measurement applications to provide metrics of signal quality
to the user. The acquisition d ata processing is performed by one of several
field-programmable gate arrays (FPGAs) under control of the processor. The
processor performs measurement applications.
The processor system consists of a COM Express PCI-based processor board and
a digital interface board that connects the processor to the acquisition board.

Trigger Inputs
RSA6100B Series Service Manual2–1
There are two coaxial trigger inputs. One is on the front panel below the display
and the other is on the rear panel. Both trigger inputs connect directly to the digital
interface board. Trigger signals are processed by an FPGA on the digital interface
board. The information from the trigger system is combined with acquisition
data by the processor system.

Waveforms, spectral traces, measurement results, and control menus are displayed

The display system consists of a display adapter board, which sends text and

The
board consists of several switching supplies that translate and balance the power
taken from the power supply module.
Power is distributed from the Power Conversion board to both the RF Deck and
the Digital Interface board.
The ON/STBY switch, located on the front panel, controls all of the power to the
instrument except for the part of the circuitry in the standby power supply.
Seven individual fans provide cooling to the RTSA. Three fans are d edicated to
the RF Deck and are controlled by the RF Interface. Two fans provide cooling
for the digital side of the instrument.
The bulk power supply module has an internal fan. Control signals to the power
supply fan are sent through the Power Conversion board from the Digital Interface
board.
A seventh fan is resident on the processor board heat sink, and is controlled by
theCOMExpressPCboard.
If Option 200 is installed, an additional fan helps cool the instrument.

To initiate an alignment:
1. Select Setup > Alignments.

The signal analyzer will run an alignment procedure. Status messages are
displayed while the alignment procedure is running. If the instrument fails the
alignment procedure, an error message will be displayed. If the instrument
fails an alignment, run Diagnostics (Tools > Diagnostics) to determine why the
alignment failed.

Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage. It also
describes how to clean the exterior and interior of the instrument. Inspection and
cleaning are done as preventive maintenance. Preventive maintenance, when done
regularly, may prevent instrument malfunction and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
instrument and using general care when operating it.
How often preventive maintenance should be performed depends on the seve
of the e nvironment in which t he instrument is used. A proper time to perform
preventive maintenance is just before instrument adjustment.

Interior Cleaning
Exterior Cleaning
Use a dry, low-velocity stream of air to c lean the interior of the chassis. Use a
soft-bristle, non-static-producing brush for cleaning around components. If you
must use a liquid for minor interior cleaning, use a 75% isopropyl alcohol solution
and rinse with deionized water.
WARNING. Before performing any procedure that follows, power down the
instrument and disconnect it from line voltage. Failure to do so could cause
personal injury, or death.
Clean the exterior surfaces of the chassis with a dr y lint-free cloth or a soft-bristle
brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl alcohol
solution. Use a swab to clean narrow spaces around controls and connectors.
Do not use abrasive compounds on any part of the chassis that may damage the
chassis.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.
CAUTION. Avoid the use of chemical cleaning agents which might damage the
plastics used in this instrument. Use only deionized water when cleaning the
menu buttons or front-panel buttons. Use a 75% isopropyl alcohol solution as a
cleaner and rinse with deionized water. Before using any other type of cleaner,
consult your Tektronix Service Center or representative.

Clean the flat panel display surface by gently rubbing the display with a
clean-room wipe (such as Wypall Medium Duty Wipes, #05701, available from
Kimberly-Clark Corporation).
If the display is very dirty, moisten the wipe with distilled water or a 75%
isopropyl alcohol solution and gently rub the display surface. Avoid using excess
orce or you may damage the plastic display surface.

in the instrument.
Power On Sel

The Power On Self Tests (POST) run automatically, every time the instrument is
powered up. If a failure is detected during this process the POST Result view will
be displayed to show which module(s) failed. (See Figure 4-3.)
