Performance Verification
Performance Verification
The procedure in this section verifies the functional operation of the GP1 GPIB
Interface module. The functional test verifies that the TG 2000 Platform
mainframe is communicating with an external GPIB controller.
Verification Interval
To ensure correct instrument operation, perform these procedures once a year.
Before performing any procedures, complete all relevant maintenance procedures
outlined in the Maintenance section of this manual.
Test Equipment Required
Required equipment is shown in Table 3–1. Equipment suggestions are given in
the example column. If you do not have the required equipment, you can return
your instrument to a Tektronix service center for performance verification.

Preparation
1. Install all modules into the mainframe if they are not already installed.
2. Power on the mainframe by setting both the rear-panel POWER switch and
front-panel ON/STANDBY switch to on.
3. Allow the mainframe and modules to warm up for at least 5 minutes before
performing any tests.

Functional Test
Setup
Do the following steps to verify that the GP1 GPIB Interface module is
communicating with a remote controller. This procedure presumes that you have
done the incoming inspection which is on page 1–2 of the GP1 GPIB InterfaceModule User Manual.
1. Connect a GPIB cable from the GP1 GPIB Interface module to a GPIB
controller or a PC with an installed GPIB card.
2. Power on the TG 2000 Signal Generation Platform. Wait for the system to
complete its power-up self tests.
3. Press the Remote button on the TG 2000 Platform mainframe.
4. If you have not done so already, set the TG 2000 Platform mainframe GPIB
address and enable GPIB communications:
a. Touch GPIB Setup on the display.
b. Enter a valid GPIB address using the keypad or knob. A valid address is
one that is not in use by any other equipment or controllers on your
GPIB bus. Valid addresses are 0 through 30.
c. Touch Quit.
d. Touch the Remote Port icon on the display until it displays GPIB.
5. Set your remote GPIB controller or PC–based GPIB software to send to the
GPIB address set for the TG 2000 Platform mainframe.

Maintenance
Maintenance
This section contains instructions and procedures for maintaining and servicing
the GP1 GPIB Interface module.
Servicing Prerequisites
Follow these guidelines when maintaining or servicing the instrument.
Only qualified service personnel may maintain or service this instrument.
Before maintaining or servicing this instrument, read the Service Safety
Summary and the Operating Information in this manual.
Electrostatic Damage Prevention
This instrument contains electrical components that are susceptible to damage
from electrostatic discharge. Static voltages of 1 kV to 30 kV are common in
unprotected environments.
CAUTION. Static discharge can damage any semiconductor component in this
instrument.
Observe the following precautions to avoid static damage:
Minimize handling of static-sensitive components.
Transport and store static-sensitive components or assemblies in their
original containers, on a metal rail, or on conductive foam. Label any
package that contains static-sensitive assemblies or components.
Discharge the static voltage from your body by wearing a wrist strap while
handling these components. Servicing static-sensitive assemblies or
components should only be performed at a static-free workstation by
qualified personnel.
Do not allow anything capable of generating or holding a static charge on the
workstation surface.
Keep the component leads shorted together whenever possible.
Pick up components by the body, never by the leads.
Do not slide the components over any surface.
GP1 GPIB Interface Module Service Manual
4–1
Maintenance
Inspection and Cleaning
Do not handle components in areas that have a floor or work surface
covering capable of generating a static charge.
Use a soldering iron that is connected to earth ground.
Use only special antistatic, suction-type or wick-type desoldering tools.
NOTE. A 2% RMA flux content solder is recommended for making repairs in this
instrument. Cleaning of rosin residue is not recommended. Most cleaning
solvents tend to reactivate the rosin and spread it under components where it
may cause corrosion under humid conditions. The rosin residue, if left alone,
does not exhibit these corrosive properties.
Preventive maintenance consists of cleaning, visual inspection, and performance
checking. The preventive maintenance schedule established for the instrument
should be based on the environment in which it is operated and the amount of
use. Under average conditions, scheduled preventive maintenance should be
performed every 2000 hours of operation.
General Care
Cleaning
Protect this module from adverse weather conditions. The instrument is not
waterproof.
CAUTION. To avoid damage to this instrument, do not expose it to sprays,
liquids, or solvents.
To avoid damage to the module circuit board, do not flex the circuit board if you
remove the board from its mounting shield. The circuit board can be damaged by
flexing. The shield provides necessary structural support to the circuit board.
The instrument should be cleaned often enough to prevent dust or dirt from
accumulating. Dirt acts as a thermal insulating blanket that prevents effective
heat dissipation, and can provide high-resistance electrical leakage paths between
conductors or components in a humid environment.
4–2
GP1 GPIB Interface Module Service Manual
Maintenance
Clean the exterior of the instrument by removing dust with a lint-free cloth. Use
care to avoid scratching the touch screen. A small, soft-bristled brush is useful to
remove dust from around the selector buttons and connectors.
For further cleaning, use a soft cloth or paper towel dampened with water. You
can use a 75% isopropyl alcohol solution for more efficient cleaning.
CAUTION. To avoid damage to the surface of this instrument, do not use abrasive
or chemical cleaning agents.
If you must clean the interior of the instrument, allow the interior to thoroughly
dry before reassembling and applying power to the instrument.
Visual Inspection
Performance Verification
After cleaning, carefully check the instrument for defective connections,
damaged parts, and improperly seated transistors or integrated circuits. The
remedy for most visible defects is obvious; however, if heat-damaged parts are
discovered, determine the cause of overheating before replacing the damaged
part.
Periodic checks of the transistors and integrated circuits are not recommended.
The best measure of performance is the actual operation of the component in the
circuit.
Instrument performance should be checked after each 2000 hours of operation or
every 12 months. This will help to ensure maximum performance and assist in
locating defects that may not be apparent during regular operation. A performance verification procedure is included in this manual.

Repackaging Instructions
Use the following instructions to prepare your module for shipment to a
Tektronix, Inc., service center:
1. Attach a tag to the instrument showing: the owner, complete address and
2. Package the instrument in the original packaging materials. If the original
phone number of someone at your firm who can be contacted, the instrument
serial number, and a description of the required service.
packaging materials are not available, follow these directions:
a. Obtain a carton of corrugated cardboard having inside dimensions six or
more inches greater than the dimensions of the instrument. Use a
shipping carton that has a test strength of at least 250 pounds (113.5 kg).
b. Place the instrument in its carrying pouch or surround the instrument
with a protective bag.
c. Pack dunnage or urethane foam between the instrument and the carton. If
using Styrofoam kernels, overfill the box and compress the kernels by
closing the lid. There should be three inches of tightly packed cushioning on all sides of the instrument.
3. Seal the carton with shipping tape, industrial stapler, or both.
