Section 1—TG 501
OPERATING
INSTRUCTIONS
INTRODUCTION
Description
The TG 501 is ageneral purpose Time Mark Generator
plug-in designed to operate in aTM 500 Series Power
Module. AVariable Timing Readout provides asimple, but
accurate means of measuring timing errors over ±7.5%
minimum range. Since many specifications are given in
percentages, the error readout eliminates the need for
computations and, additionally, lessens parallax discrep-
ancies.
Marker selection from 5sthrough 1ns in a1,2,5,
sequence is available. 5sthrough 10 ns markers are selected
by arotary switch. 5,2, and 1ns modified sine waves are
selected by self-canceling push-buttons when the rotary
switch is in the 52 IN position.
All outputs are available at the front-panel connectors or
by modification of the interface connector, located at the
back of the plug-in, and the TM 500 Series Power Module.
Power supplies are current limited. The 5volt supply is
over-voltage protected to avoid damage to the integrated
circuits.
Installation
The TG 501 is calibrated and ready for use when
received. Referring to Fig. 1-1, install the Generator and
turn on the Power Module. Check the front-panel of the
Generator to see that the knob skirt is lighted. The TG 501
is designed to operate in any compartment of aTM 500
Fig. 1-1. Plug-in Installation and Removal.

Operating Instructions—TG 501
Series Power Module. Refer to the Power Module Instruc-
tion Manual for line voltage requirements and Power
Module operation.
NOTE
It is recommended that the Power Module be turned
off before inserting or removing the TG 501. Arcing
at the connector terminals can reduce connector life.
However, no interna! damage will result if the
Generator is inserted into alive Power Module.
Refer to the Controls and Adjustments fold out page for
front-panel controls, connectors and indicator descriptions.
OPERATING CONSIDERATIONS
The internal reference of the TG 501 is a1MHz crystal.
If Option 1is ordered, ahigh accuracy 5MHz crystal is
provided and Integrated Circuit, U50 is installed on the
back of the main circuit board. Provisions are made for
buffered output of either 1MHz or 5MHz internal clock
through interface connector pin 25A with associated
ground on pin 26A.
A1MHz, 5MHz or 10 MHz external clock can be
substituted. To use an external 5or 10 MHz clock, U50
must be installed on the back of the main circuit board and
the necessary jumpers added (see Fig. 1-2) to divide down
the input to meet the 1MHz internal requirement. U50 is
not required for a1MHz external clock, but jumpers must
be added.

be installed to use the TG 501 with the various clock
choices. The required jumpers are:

OPERATING MODES
Calibrated Mode
When center-button of VARIABLE TIMING Control is
pushed in, the MARKER Control selects calibrated marker
intervals from 5sto 10 ns indicated by the lighted knob
skirt. To select 5, 2or 1ns modified sine wave markers, set
MARKER Control to 52 IN position and depress desired
pushbutton.
Variable Timing Mode
When center button of VARIABLE TIMING Control is
out, output timing is faster or slower than the calibrated
marker to the percentage indicated by the VARIABLE
TIMING READOUT Display and the FAST-SLOW Indica-
tor lights. 5, 2and 1ns push-button controlled modified
sine waves are not variable and Readout Display is turned
off when MARKER Control is in 521N position.
Readout Display Test
To check the operation of the display LED's (Light-
Emmiting Diodes), fully depress the center button of the
VARIABLE TIMING Control (push in firmly). All LED
segments should light, displaying 8.8 in the Readout.
TYPICAL APPLICATIONS
The TG 501 can be used for many applications not
described in the manual. Use the following examples to
become familiar with the TG 501's VARIABLE TIMING
READOUT. Contact your Tektronix Field Office or rep-
resentative for making specific measurements with this
instrument.
Time Base Measurements
To accurately determine the timing error of atime base:
1. Connect the MARKER OUT of the TG 501 to the
Vertical Input of the oscilloscope. Use a50 coaxial cable
terminated into 50 SI.
2. connect the TRIGGER OUT of the TG 501 to the
External Trigger Input of the time base. Use a50 S2 coaxial
cable terminated into 50 S2.
3. Select external trigger source on the time base.
4. Select, for example, 1jjis sweep rate of the time base.
5.
Set MARKER Control rotary switch of TG 501 to
1/is.
6.
Make sure center button of VARIABLE TIMING
Control, concentric with MARKER Control, is out (Vari-
able Timing Mode).
7.
Use Horizontal Position control of time base to make
first time mark coincide with first graticule line on the
oscilloscope. See Fig. 1-3.
8.
Rotate VARIABLE TIMING knob until all time
markers coincide with graticule lines on the oscilloscope, as
shown in Fig. 1-4.

9.
Either the FAST or SLOW Indicator will light
showing whether the time base is faster or slower than the
calibrated markers of the TG 501. Read the percentage of
error from the VARIABLE TIMING READOUT Display.
Pulse Generator Measurements
To accurately determine pulse duration or period of a
Pulse Generator.
1.
Adual-trace vertical oscilloscope is required. Select
alternate mode.
2.
Connect the MARKER OUT of the TG 501 to one
channel of the dual-trace oscilloscope. Use a50 coaxial
cable terminated into 50 L2.
3.
Connect the Output of the pulse generator to the
other channel of the dual-trace, using a50 coaxial cable
terminated into 50 i2.
4.
Set the time/div switch to display 1cycle of apulse
in 10 divisions of the graticule on the oscilloscope, as
indicated in Fig. 1-5.
5.
Use the MARKER Control switch of the TG 501 to
display one time marker approximately at pulse duration

and one at pulse period. Align first time marker with
beginning of pulse wave-form. See Fig. 1-5.
6.
Select Variable Timing Mode on the TG 501, VARI-
ABLE TIMING Control center button out.
7.
Use the Vertical Position control of the oscilloscope
to set the peaks of the time markers at 50% amplitude of
pulse shown in Fig. 1-5.
8.
To check the timing of pulse duration, rotate the
VARIABLE TIMING knob until time marker coincides
with pulse duration, as shown in Fig. 1-6.
9. Either the FAST or SLOW Indicator will light,
showing whether the pulse duration of the pulse generator
is faster or slower than the calibrated time mark of the
TG 501 .Read the percentage of error from the VARIABLE
TIMING READOUT Display.
10. To check the timing of pulse period, rotate the
VARIABLE TIMING knob until time marker coincides
with pulse period. See Fig. 1-7.

MECHANICAL REPLACEABLE PARTS LIST
PARTS ORDERING INFORMATION
Replacement parts are available from or through your
local Tektronix, Inc. Field Office or representative.
Changes to Tektronix instruments are sometimes made
to accommodate improved components as they become
available, and to give you the benefit of the latest circuit
improvements developed in our engineering department. It
is therefore important, when ordering parts, to include the
following information in your order: Part number, instru-
ment type or number, serial number, and modification
number if applicable.
If apart you have ordered has been replaced with anew
or improved part, your local Tektronix, Inc. Field Office or
representative will contact you concerning any change in
part number.
Change information, if any, is located at the rear of this
manual.
SPECIAL NOTES AND SYMBOLS
XOOO Part first added at this serial number
OOX Part removed after this serial number
FIGURE AND INDEX NUMBERS
Items in this section are referenced by figure and index
numbers to the illustrations.
INDENTATION SYSTEM
This mechanical parts list is indented to indicate item
relationships. Following is an example of the indentation
system used in the description colurnn.
12345Name &Description

Parts of Detail Part
Attaching parts for Parts of Detail Part
Attaching Parts always appear in the same indentation as
the item it mounts, while the detail parts are indented to
the right. Indented items are part of, and included with, the
next higher indentation. The separation symbol —*—
indicates the end of attaching parts.
Attaching parts must be purchased separately, unless
otherwise specified.
ITEM NAME
In the Parts List, an Item Name is separated from the
description by acolon (:). Because of space limitations, an
Item Name may sometimes appear as incomplete. For
further Item Name identification, the U.S. Federal
Cataloging Handbook H6-1 can be utilized where possible.
