1. Introduction
SM01 is a video encoder and pattern generator supporting standard
definition video standards.
As a video pattern generator, SM01 can generate 15 NTSC, 15 PAL and 15
960H line based patterns, a zone plate generator, and a programmable
12MHz maximum horizontal frequency sweep. These are output as
simultaneous SDI (SMPTE-259M –NTSC/PAL only), YPbPr component,
NTSC-M/J/443 or PAL-M/60 (for 525 line standards) or PAL-BG/I or PAL-N
(for 625 line standards) or 960H (NTSC or PAL) or 1280H (NTSC or PAL –
zone plate, vertical and horizontal sweep only) formats.
Patterns available include:
75%/100%/SMPTE/Bars+Red colour bars
Black/White/50% grey flat fields
2T, 20T and Pulse bar
CCIR17/18/330 and 331
FCC Comp and FCC MB
N7C MBF and N7C MPF
Ramp
Multi-burst
Horizontal (up to 12MHz) and Vertical Sweeps
5/10 step linearity
Pathological (SDI test)
Gamut
Bowtie
Circular Zone Plate
In addition programmable amplitude noise may be added to the CVBS
pattern output. Noise can be 50Hz or 60Hz hum and/or white noise.
As a video encoder SM01 accepts 525 or 625 line SMPTE-259M inputs
which it encodes to simultaneous SDI (SMPTE-259M), YPbPr component
and NTSC-M/J/443, PAL-M/PAL-60 (525 line standards) or PAL-BG/I, PAL-
N (for 625 line standards). Again noise may be added to the CVBS output.

Controls provided include:
CVBS amplitude
CVBS Luma amplitude
CVBS Chroma amplitude
CVBS Burst amplitude
CVBS Sync amplitude
CVBS Black level
NTSC Hue (Chroma phase)
CVBS subcarrier frequency
YPbPr Luma amplitude
YPbPr Chroma amplitude
YPbPr Sync amplitude
YPbPr Black level
SM01 is powered by a universal input power supply and controlled with a
simple and intuitive selection menu.

2. Connecting up the SM01
All connections to the SM01 are made via the rear panel: see Figure 1.
Figure 1 SM01 rear panel.
The AC-DC converter connects to the left hand jack. The SM01 input is
protected against reverse polarity. The converter supplied with the SM01 is
a model MW173KB manufactured by SL Power Electronics Corp. and
provides 9VDC at 3A and accepts AC inputs from 100-240VAC. Connect
the supplied power cord to the AC-DC converter and output DC of the
converter to the 9VDC Power In input of the SM01.

3. Quick Start Guide
Switch On and Control
Connect the AC-DC converter 9VDC cable into the rear panel power in
socket. Connect the AC supply to a local AC supply between 110-240VAC.
The Standby LED should light. Push the Adjust control and the unit will
switch on and the welcome message will be displayed (SingMai SM01).
To switch off the SM01 push the Adjust control again.
The front panel of the SM01 is shown in Figure 3.
Figure 3 SM01 Front panel.
There are just two controls for the SM01. The right hand control (Adjust)
switches the unit between On and Standby by pushing it whilst also
adjusting the value of parameters by rotating the knob left or right. The
central switch (Select) selects the chosen menu parameter and switches
preset parameters between, for example, on and off.
After the welcome message (‘SingMai, SM01’) is displayed for a few
seconds the LCD display will show the available top level menus. A left
hand arrow indicates which menu is ‘active’. Rotating the Adjust control will
show all the available menus; after the last of the menus an up arrow is
shown.
To select a menu ensure the left arrow is by the side of the required top
level menu and press the Select button. Those menu options will then be
displayed.

11
To change a parameter within the lower menu choices choose the required
item by aligning the left arrow with it and press the Select button. The
parameter will either toggle between the available options (e.g. On or Off)
or will show a menu bar where to can select more options via the Adjust
control. Once you have chosen the setting you require press the Select
button to return to the menu choices.
The Adjust control is also used to set the parameter values. Once set the
required value, press the Select button to retain that value and return to the
menu.
To return to the top level menu scroll down the menu choices using the
Adjust control; the last one before the up arrow will show Exit. Select this
by pressing the Select button and you will return to the top level menus.

12
Menu control
The complete menu structure is shown in Figure 4.
Figure 4 SM01 Menu structure.

13
The following is a brief description of the menu functions.
SDI in:
Pattern (Encoder)
Each button press toggles between the internal patterns (Pattern –default
value) and the serial digital (SDI) input (Encoder).
(Note: the SDI input is not operative for the 960H or 1280H standards.)
Exit
Returns to the top level menus.
Stand’d (Standard):
In Encoder mode the SDI input standard must match the output
standard selection. (i.e. if the SDI input is 625 line standard, selecting
NTSC-M/J/443/PAL-60 or PAL-M will result in corrupted outputs).
NTSC-M
Forces NTSC-M output standard for the composite output and 525 line
standard for the YPbPr and SDI outputs. (Default value)
NTSC-J
Forces NTSC-J output standard for the composite output and 525 line
standard for the YPbPr and SDI outputs. (NTSC-J is the Japanese version
of NTSC, which has no setup and different output levels to NTSC-M).
NTSC443
Forces NTSC443 output standard for the composite output and 525 line
standard for the YPbPr and SDI outputs. (NTSC-443 is a playback
‘standard’ which has NTSC timing characteristics with a 4.433MHz PAL
subcarrier frequency).
PAL-BG
Forces PAL-BG output standard for the composite output and 625 line
standard for the YPbPr and SDI outputs.
PAL-I
Forces PAL-M output standard for the composite output and 525 line
standard for the YPbPr and SDI outputs.

14
(Note the difference between PAL-BG and PAL-I is only the front porch
value).
PAL-N
Forces PAL-N output standard for the composite output and 625 line
standard for the YPbPr and SDI outputs.
PAL-60
Forces PAL-60 output standard for the composite output and 525 line
standard for the YPbPr and SDI outputs. (PAL-60 has NTSC timing
characteristics but with a PAL 4.43 subcarrier frequency and PAL phase
alternate line switching).
NTSC960
Forces NTSC-M output standard for the composite output and 525 line
standard for the YPbPr outputs. (Note the 960H sampling frequency is
36MHz).
PAL-960
Forces PAL-BG output standard for the composite output and 625 line
standard for the YPbPr outputs. (Note the 960H sampling frequency is
36MHz).
NTSC128
Forces NTSC-M output standard for the composite output and 525 line
standard for the YPbPr outputs. (Note the 1280H sampling frequency is
54MHz).
PAL1280
Forces PAL-BG output standard for the composite output and 625 line
standard for the YPbPr outputs. (Note the 1280H sampling frequency is
54MHz).
Exit
Returns to the top level menus.
The specifications for the standards are shown in Appendix A.

15
Pattern:
Selects the output pattern when in ‘Pattern’ mode. (In ‘Encoder’ mode the
pattern menu cannot be selected.)
The patterns available depend on the standard selected. Table 5 lists the
patterns available for each standard. A full description of the patterns can
be found in Chapter 4.
Table 5 SM01 Patterns.

16

4. SM01 Patterns
Below is a detailed description of each of the SM01 patterns.
(Note: The NTSC/PAL 1280H standards only provide a set of
programmable frequency sweeps that allow the performance of this
standard’s extended luma bandwidth to be measured. The description of
these patterns are at the end of this chapter.)
75% Colour bars
75% colour bars are used for measuring insertion gain, chroma level and
chroma gain and for monitor alignment. The SM01 generates full frame
75% saturated colour bars with a 100% white bar reference and 7.5 IRE
setup (for the NTSC-M/PAL-M composite output only). The colour bar
sequence is white, yellow, cyan, green, magenta, red, blue and black.

100% Colour bars
100% colour bars are used for measuring insertion gain, chroma level and
chroma gain and for monitor alignment. The SM01 generates full frame
100% saturated colour bars with a 100% white bar reference and 7.5 IRE
setup (for the composite output only). The colour bar sequence is white,
yellow, cyan, green, magenta, red, blue and black.
Note that 100% NTSC colour bars will cause clipping in the transmitter and
they are therefore only used within a studio ‘closed system’.
