Section 1—SG 5010
SPECIFICATION
introduction
This section of the manual contains a general description
of the TEKTRONIX SG 5010 Programmable 160 kHz Oscil¬
lator and its electrical, environmental, and physical speci¬
fications. Standard accessories are also listed. Instrument
option information is located in the Options section.
Instrument Description
The SG 5010 Programmable 160 kHz Oscillator is a
GPIB programmable TM 5000-Series plug-in instrument de¬
signed for low-distortion audio applications, It generates five
waveforms: sine wave, square wave, SMPTE/DIN
intermodulation test signal, CC1F intermodulation test sig¬
nal, and sine wave burst. All of these signals may be swept
in frequency or amplitude. Frequency, amplitude, and burst
parameters are fully programmable, as are the sweep pa¬
rameters. Parameter values are displayed by 5 seven-seg¬
ment LEDs in the display window. The window also
indicates parameter units, remote or addressed state, and
error codes. Three source impedances are selectable and
the output signal can be grounded or floating, balanced or
unbalanced. Output amplitude is programmable from
0.2 mV to 21.2 V peak equivalent Vrms (10.6 Vrms maxi¬
mum in unbalanced mode), supplying up to 28 dBm into a
600 Q load. An ON-OFF function turns the output signal on
or off at the output connectors. Additional connectors sup¬
ply a sync signal, sweep ramp and pen lift signals and ac¬
cept triggering and input signals from external sources.
At power-up, the instrument performs a self-test and as¬
sumes the settings in use when previously powered-down,
with the exception that the output is in the “OFF" condition
and the display shows the amplitude. Instrument functions
can be set to ten user-definable configurations stored in
memory.
The SG 5010 is designed for remote or local operation in
two compartments of any TM 5000-Series power module. It
can also operate under local control only, in two compart¬
ments of a TM 500-Series power module, after minor me¬
chanical modification (refer to qualified service personnel).
Rear interface connections provide access to versions of all
front panel signals except the main output.

IEEE 488 (GPIB) Functions
The SG 5010 can be remotely programmed via the digital
interface specified in IEEE Standard 488-1978, IEEE Stan¬
dard Digital Interface for Programmable Instrumentation. In
this manual, the digital interface is called the General Pur¬
pose Interface Bus (GPIB).
The IEEE standard identifies the interface function reper¬
toire of an instrument on the GPIB in terms of interface func¬
tion subsets. The subsets are defined in the standard. The
subsets that apply to the SG 5010 are listed in Table 1-1.

OPERATING INSTRUCTIONS
Introduction
This section of the manual provides installation and re¬
moval instructions and describes the functions of the
SG 5010 front-panel controls and connectors. Operators fa¬
miliarization information is also provided as an aid in under¬
standing how to operate the SG 5010 under local (manual)
control only.
NOTE
The information in this section assumes the instru¬
ment is not connected to the GPIB via the power
module.
Complete information for programming the SG 5010 via
the GPIB (General Purpose Interface Bus) is found in the
Programming section of this manual.
PREPARATION FOR USE
Installation and Removal
The SG 5010 is calibrated and ready for use when re¬
ceived. Make certain the line selector block on the power
module is positioned correctly. The SG 5010 is designed to
operate in a TM 5000-Series power module, it can aiso op¬
erate under local (manual) control only, in a TM 500-Series
power module; however, minor mechanical changes must
first be made to the instrument. Refer qualified personnel to
the Maintenance section of this manual for instructions on
making the modifications for operation in a TM 500 Series
power module.
To prevent damage to the SG 5010, turn off the
power module before installing or removing the instru¬
ment. Do not use excessive force to install or remove.
Check to see that the plastic barriers on the intercon¬
necting jacks of the selected power module compartments
match the cutouts in the SG 5010 rear interface connectors.
If they do not match, do not install the SG 5010 until the
reason is investigated. When the units are properly
matched, align the SG5010 chassis with the upper and
lower guides of the selected compartments (see Fig. 2-1).
Push the SG 5010 chassis in and press firmly to seat the

To remove the SG 5010 from the power module, pull out
on the release latch (located in the lower left corner) until the
interconnecting jacks disengage and the SG 5010 slides
out.
Repackaging For Shipment
If the instrument is to be shipped to a Tektronix Service
Center for service or repair, attach a tag listing the owner
(with address), and the name of an individual at your firm
that can be contacted. Include tomplete instrument serial
number and a description of the service required.
If the original package is unfit for use or unavailable, repack¬
age the instrument as follows:
Surround the instrument with polyethylene sheeting or
other suitable material to protect the exterior finish. Ob¬
tain a carton of corrugated cardboard of adequate
strength and having inside dimensions no less than six
inches more than the dimensions of the instrument.

Cushion the instrument by tightly packing dunnage or
urethane foam between the carton and instrument, on all
sides. Seal the carton with shipping tape or an industrial
stapler.
The carton test strength for this instrument is 200 lbs.
FRONT PANEL CONTROLS,
CONNECTORS AND DISPLAY
All controls necessary for local operation of the SG 5010
are located on the instrument front-panel. Many push¬
buttons illuminate to provide visual indication that associ¬
ated functions are active. A brief description of these
controls and indicators follows. Refer to Fig. 2-2.
DISPLAY INDICATORS
The SG 5010 uses seven-segment LED's to display a
numerical value of up to five digits. In addition, LED indi¬
cators in the right area of the display window illuminate,
when appropriate, to indicate units of measure for param¬
eters, GPiB operation, and error events.
PARAMETER UNITS OF MEASURE
Units for the displayed value are defined by an illumi¬
nated units indicator in the readout window. These units
are:

@ PARAMETER
Each pushbutton in this group enables either a primary or
secondary parameter; the current value and units for the
selected parameter are indicated in the display window.
These pushbuttons are mutually exclusive.
To enable a primary parameter {nomenclature above but¬
ton), press the associated parameter button. The button for
the selected primary parameter illuminates.
To enable a secondary parameter (nomenclature to the
right of button), press the PARAMETER SHIFT button be¬
fore pressing the desired parameter button. Both the se¬
lected parameter button and the PARAMETER SHIFT
button illuminate.
The value of the selected parameter (primary or second¬
ary) may be changed by entering a new value (using the
numeric keyboard and pressing ENTER) or adjusted by ro¬
tating the DEC/INC control. The units buttons (secondary
functions of some numeric buttons) alternate the units.
Vrms (START VOLT)
dBm (STOP VOLT)
Allows the operator to set the amplitude of the output
signal in volts rms open circuit, or dBm into an assumed
600 0 load. The maximum output is 10.6 Vrms
(+22.05 dBm) unbalanced, and 21.2 Vrms ( + 28.05 dBm)
balanced. The dBm display compensates for the source im¬
pedance, assuming a 600 Q load. The voltage displayed is
the open circuit voltage.
Units are volts rms or millivolts rms (mV./kHz button), or
decibels, depending upon the parameter selected.
START VOLT (secondary parameter) sets the starting
amplitude in Vrms for the sweep mode; STOP VOLT sets
the final amplitude of the swept waveform.
FREQ (START FREQ)
Allows the operator to set the main frequency of the out¬
put signal (except EXT) using Hz or kHz units.
START FREQ (secondary parameter) sets the frequency
at which the sweep begins. Units are Hz, or kHz (mV/kHz
button).
IM FREQ triangle (STOP FREQ)
Allows the operator to set the low or offset frequency for
the SMPTE/DIN and CCIF functions. In the SMPTE/DIN
function, the IM FREQ is the frequency of the lower tone. In
the CCIF function, the IM FREQ is one-haif of the difference
frequency between the two test tones. Frequency can be
40, 50, 60, 80, 100, 125, or 500 Hz. The instrument rounds
off an entered frequency to the nearest legal frequency, un¬
less the entry is beyond specified limits; the latter causes
the ERR button to light and the entry is not accepted.
STOP FREQ (secondary parameter) sets the frequency
at which the sweep stops.
ON CYCLES (N STEPS, LIN/LOG)
Allows the operator to set the number of on cycles for
the BURST function. The minimum is 1; maximum is
65,535.
N STEPS (secondary parameter) sets the number of
steps (1 to 99) from START FREQ to STOP FREQ. In addi¬
tion, a linear or logarithmic type of sweep can be selected
(LIN/LOG button). The selected sweep type is indicated by
Li or Lo in the display window.
OFF CYCLES (STEPTIME, AMP/FREQ)
Allows the operator to select the number of off cycles for
the BURST function. Minimum number is 1; maximum is
65,535. Selecting 0 enables gated burst operation using the
BURST GATE input. Selecting 99999 enables triggered
burst operation using the BURST GATE input.
STEPTIME (secondary parameter) sets the time (in sec¬
onds) for each SWEEP step. The minimum time is 0.1 sec¬
onds; maximum is 25.0 seconds, in increments of 0.1
seconds. The sweep mode (amplitude or frequency) is se¬
lected by pressing AMP/FREQ.

OPERATORS FAMILIARIZATION
General Operating Information
With the SG 5010 properly installed in the power module,
allow twenty minutes warmup time for operation to specified
accuracy; 60 minutes after storage in or exposure to a high
humidity (condensing) environment.
Power-up Sequence
When powered up, the SG 5010 performs a diagnostic
self-test to check the functionality of the instrument ROM
and RAM, and some hardware circuits. It also illuminates all
front panel LED and indicators. If a self-test error is de¬
tected, a three digit error code appears in the readout win¬
dow, indicating an internal malfunction. Should this occur,
refer the condition to qualified service personnel. The
SG 5010 does not respond to front panel controls until the
error is cleared. Pressing the CLEAR button clears the error
code from the readout window and allows the instrument to
complete initialization, but does not dear the condition caus¬
ing the error code.
