Owners of TVS600 model waveform analyzers may purchase a firmware
upgrade kit that adds most of the features of the TVS600A models. Contact your
Tektronix service representative for more information (see Contacting Tektronix
on page xv).
NOTE. This manual ships with the TVS600A version of the VXIplug&play
software; TVS600 Waveform Analyzers with version 2.0 or earlier firmware
cannot use all the features supported by the VXIplug&play driver and Soft Front
Panel. You may prefer to use your previous versions of the driver and Soft Front
Panel or, you may prefer to upgrade your firmware (see Firmware Upgrade,
above).
The waveform analyzer is a VXIplug&play instrument and comes with
VXIplug&play software that runs on the Win, Win95, and WinNT platforms.

You must configure the VXIbus module and the VXIbus mainframe before
installing the module. To configure the waveform analyzer, set its logical address
on the VXIbus. To make ready your VXIbus mainframe, you ensure power and
capacity requirements are met. You may also have to set the Bus Grant and
Interrupt Acknowledge jumpers, if your mainframe uses them. This section
describes how to perform the necessary configuration.
Every module within a VXIbus system must have a unique logical address; no
two modules can have the same address. On the waveform analyzer, you rotate
two switches on the rear panel to select the logical address. Refer to Figure 1–3
for the switch locations. You can select a static address or Dynamic Auto
Configuration. The default address is FF hexadecimal, which selects Dynamic
Auto Configuration.
1–6
Static Logical Address. Static logical address selections set the address to a fixed
value. The range for static addresses is from 01 to FE hexadecimal (1 to 254
decimal). A static logical address ensures that the waveform-analyzer address
remains fixed for compatibility with systems that require a specific address
value. Remember that each device within your system must have a unique
address to avoid communication problems. The factory default address is
FF hexadecimal, which selects Dynamic Auto Configuration.
TVS600 & TVS600A Series Waveform Analyzers User Manual
Installation
Dynamic Auto Configuration. With Dynamic Auto Configuration selected
(hexadecimal FF or decimal 255), the system resource manager automatically
sets the address to an available value in your system. For example, if you already
have devices set to addresses 01 and 02, the resource manager might automatically assign address 03 to the waveform analyzer at power on.

This section describes how to install the waveform analyzer into a Tektronix
VXIbus mainframe. If you are installing the waveform analyzer into a different
mainframe, refer to the instruction manual for that mainframe for any pertinent
installation or capacity information.
V oltage, Current, and Cooling Requirements. You will find voltage, current, and
cooling requirements for the waveform analyzer in Appendix A: Specifications at
the following locations:
Voltage and current requirements. See Table A–6 on page A–12.
Cooling requirements. See Airflow Resistance in Table A–7 on page A–13.

Installation
These requirements also appear on the left cover of the waveform analyzer. Be
sure your mainframe can supply adequate current and cooling to the waveform
analyzer as well as the other modules you plan to install into the same mainframe.
WARNING. Shock hazards exist due to high currents within the mainframe
compartment. Do not change configuration of the Bus Grant and Interrupt
Acknowledge jumpers unless you are qualified to do so. Consult your VXI
mainframe manual for safety warnings and configuration information.
Jumper Settings. Most newer VXIbus mainframes, such as the Tektronix
VX1410 Intelliframe, have an auto-configurable backplane with no mechanical
jumpers. You do not need to set jumpers on these VXIbus mainframes.
Some earlier VXIbus mainframes contain daisy-chain jumper straps that you
must configure before installing the waveform analyzer. The jumper straps,
located beside the P1 connectors, set up the Bus Grant (BG0–BG3) and Interrupt
Acknowledge (IACK) signals. If you are using a Tektronix mainframe that uses
such straps, the names of the jumper straps (BG0–BG3 and IACK) are often
printed on the circuit board facing the front of the mainframe. Access these
jumpers from the front of the mainframe.
Hardware Installation
If your VXIbus mainframe has jumper straps, set the IACK and BG0–BG3
jumpers for the waveform analyzer as described below:
Remove the jumper straps for the left-most slot in which you will install the
waveform analyzer (retain the strap for future configurations).
Leave the jumpers for the right-most slot installed in the mainframe.
For example, if you want to install the waveform analyzer into the third and
fourth mainframe slots, remove all jumper straps for the third slot and make sure
the jumpers are installed in the fourth slot.
This section describes how to install the waveform analyzer into a VXIbus
mainframe and how to install the product software. For hardware configuration
information, refer to Hardware Configuration on page 1–6.
You may install the waveform analyzer into any empty slot in the mainframe
except Slot 0. Be sure to set the logical address before installation (see Setting
the Logical Address on page 1–6).

TVS600 & TVS600A Series Waveform Analyzers User Manual
Installation
CAUTION. If you install the waveform analyzer into a D-size mainframe, be sure
to connect the P1 and P2 connectors of the module to the P1 and P2 connectors
on the mainframe. Electrical damage will result if you connect the P1 and P2
connectors on the module to the P2 and P3 connectors on the mainframe.
To avoid damage, check for bent pins on P1 and P2 before installation.
Use the following installation procedure and Figure 1–4 on page 1–10 to install
the waveform analyzer into the mainframe:
1. On the mainframe, set the power ON/STANDBY switch to STANDBY.
2. Insert the waveform analyzer into the mainframe top and bottom module
guides and push it partially into the mainframe (Figure 1–4). Then slide the
waveform analyzer into the mainframe as far as it will go without forcing it.
3. Make sure the front panel is flush with the front of the mainframe chassis,
and then use a flat-blade screwdriver to install the top and bottom retainer
screws. Alternately tighten the screws, applying only a few turns at a time to
fully seat the module. If it is not flat, remove the module and check for
mechanical problems with the VXIbus connector or the module enclosure.
