OPERATORS SAFETY SUMMARY
The general safety information in this part of the summary is
for both operating
and servicing personnel. Specific
warnings
and cautions will be found throughout the manual
where they apply, but may not appear in this summary.
TERMS
In This Manual
CAUTION statements identify conditions or practices that
could result in damage to the equipment or other property.
WARNING statements identify conditions or practices that
could result in personal injury or loss of life.
As Marked on Equipment
CAUTION indicates a personal injury hazard not immediate-
ly accessible as one reads the marking, or a hazard to prop-
erty including the equipment itself.
DANGER indicates a personal injury hazard immediately ac-
cessible as one reads the marking.
SYMBOLS
In This Manual
This symbol indicates where applicable cau-
tionary or other information is to
be found.
As Marked on Equipment
vi
f DANGER -High voltage.
@ Protective ground (earth) terminal.
.& ATTENTION -refer to manual.
Power Source
This product is intended to operate from a power module
connected to a power source that will not apply more than
250 volts rms between the supply conductors or between
either supply conductor
and ground. A protective ground
connection
by way of the grounding conductor in the power
cord is essential for safe operation.
Grounding the Product
This product is grounded through the grounding conductor
of the power module power cord. To avoid electrical shock,
plug the power cord into a properly wired receptacle before
connecting to the product input or output terminals. A pro-
tective ground connection
by way of the grounding conduc-
tor
in the power module power cord is essential for safe
operation.
Danger Arising From Loss of Ground
Upon loss of the protective-ground connection, all accessi-
ble conductive parts (including knobs and controls that may
appear to
be insulating) can render an electric shock.
Use the Proper Fuse
To avoid fire hazard, use only the fuse of correct type, volt-
age rating and current rating as specified in the parts list for
your product.
Refer fuse replacement to qualified service personnel.
Do Not Operate in Explosive Atmospheres
To avoid explosion, do not operate this product in an explo-
sive atmosphere unless it has been specifically certified for
such operation.
Do Not Operate Without Covers
To avoid personal injury, do not operate this product with-
out covers or panels installed.
Do not apply power to the
plug-in via a plug-in extender.

SERVICE SAFETY SUMMARY
FOR QUALIFIED SERVICE PERSONNEL ONLY
Refer a/so to the preceding Operators Safety Summary.
Do Not Service Alone
Do not perform internal service or adjustment of this prod-
uct unless another person capable of rendering first
aid and
resuscitation
is present.
Use Care When Servicing With Power On
Dangerous voltages may exist at several pOints in this prod-
uct. To avoid personal injury, do not touch exposed connec-
tions and components while power
is on.
@
Disconnect power before removing protective panels, sol-
dering, or replacing components.
Power Source
This product is intended to operate in a power
moduleconnected to a power source that will not apply
more than 250 volts rms between the supply conductors or
between either supply conductor and ground. A protective

Section 1-PG 507
SPECIFICATION
Introduction
The TEKTRONIX PG 507 50 MHz Dual Output Pulse
Generator is designed to operate in any two compartments
of a TM 500-series power module. It
is a general purpose,
full function pulse generator, designed for digital logic
applications.
Important features include dual simultaneous comple-
mentary pulse outputs with a maximum amplitude of 15
volts in a ± 15 volt window from a low reactance 50 r.
source, 3.5 ns rise and fall times, and independent control of
the high
and low levels of the output pulse.
Front panel controls and connectors provide the capabili-
ty to trigger or synchronously gate the PG 507 from an ex-
ternal signal with trigger/gate input level and slope controls.
Delayed pulse, paired pulse, and manual trigger capabilities
are included. Square-wave outputs and complementary rec-
tangular pulse outputs
can also be selected.
All inputs and outputs are internally terminated
in 50 n
except the trigger/gate input which is internally selectable
for either 50 n or 1 Mn, 20 pF input impedance. A control
error warning light indicates incompatible control settings.
Special positions on the period, duration, and delay controls
permit customized control ranges.
C(l>
The high and low level pulse amplitude controls are
shared by both outputs,
and a preset switch allows selec-
tion of adjustable preset output levels. Each of the outputs
has
an independent normal/complement switch.
The rear interface connector provides access to several
internal signals and provides control lines that permit cus-
tom interconnecting of companion instruments.
Performance Conditions
The performance limits in this specification are valid with
the following conditions:
1. The instrument must have been adjusted at an ambi-
ent temperature between +20°C and +30°C.
2. The instrument must be in a non-condensing environ-
ment whose limits are described under Environmental.
3. Allow thirty minutes warm-up time for operation to
specified accuracy; sixty minutes after exposure to or
storage
in high humidity (condensing) environment.
Items listed in the Performance Requirements column of
the Electrical Characteristics are verified by completing the
Performance Check in the Calibration Section of this man-
ual. Items listed
in the Supplemental Information column are
not verified
in this manual. They are either explanatory
notes or performance characteristics for which no limits are
specified.

OPERATING INSTRUCTIONS
INSTALLATION INSTRUCTIONS
Preparation for Use
The PG 507 50 MHz Dual Output Pulse Generator is
calibrated and ready
for use when received. It is a plug-in
designed to operate in any two compartments of aTM 500
series power module. Refer to the power module i nstruc-
tion manual for line voltage requirements and power
module operation. A list of standard accessories (and part
numbers) is located in
the back of this manual.
Several internal changes are available
to modify the
PG 50Ts capabilities. Each item is described in the
Operators Familiarization part of
this section of the
manual. Refer all internal changes to qualified service
personnel. Qualified service personnel see the
Maintenance section
of this manual for more information.
The following is a list of items that are affected by these
internal changes.
@
Front Panel Functions/Controls
PERIOD and DURATION controls. One range can
be custom selected for each control.
DELAY
control. One range can be custom selected.
TRIG/GATE IN. Input impedance selection.
+ TRIG OUT -Can be internally set for normal or
complement trigger.
Rear I nterface Signals
External Voltage Control.
Trig/Gate Input.
Trigger Output.
Turn the power module off before inserting or
removing the plug-in to prevent damage to the plug-
in circuitry.
Check to see that the plastiC barriers on the inter-
connecting jack of the selected power module compart-
ment match the cutouts in the PG 507 circuit board edge
connector. Align the PG 507 chassis with the upper and
lower guides (see Fig. 2-1) of the selected compartments.
Push the PG 507 chassis in and press firmly to seat the
ci rcuit board edge connector in the i nterconnecti ng jack.
Pullout the power switch on the power module. The
PG 507 POWER indicator light on the front panel should
light.
To remove the PG 507, turn off the power module and
pull on the release latch (located in the lower left corner)
until the interconnecting jack disengages and the PG 507
slides out.
