making it ideal for analyzing modern and legacy signal paths. It can analyze video signals up to 8K/60 Hz
and 4K/120 Hz. The onboard OLED screen and new level-switch interface offer an intuitive navigation
experience, displaying a real-time thumbnail of the source signal, along with detailed video and audio
parameters including resolution, timing, color space, audio type, sampling rate, and more.
Designed for maximum flexibility in the field, the MU-STIX-AF features low power consumption and is USB
Type-C powered, enabling operation from mobile devices, displays, or AV receivers. Rugged, reliable, and
enhanced for usability, the MU-STIX-AF is an essential tool for professional-grade HDMI signal
diagnostics.
Features
• Cost-effective HDMI 2.1b, 8K 48 Gbps (FRL) compliant signal analyzer
• Analyze signals up to 8K resolution timings at 8-, 10-, and 12-bit color depths, in RGB 4:2:0, 4:2:2,
and 4:4:4 color spaces
• Automatically detects and logs signal changes, sync losses and signal loss time
• OLED color screen with an intuitive navigation menu displays incoming video thumbnail, source
timing, FRL or TDMS presence, color space, color depth, and HDCP 1.4/2.X versions
• Displays audio information, including audio type, sampling rate and number of channels

Signal Monitor Screen
The Signal Monitor screen consists of three fields that pertain to the health of the HDMI signal and the
device uptime. This is useful for checking changes in video signal or dropped connections, these fields
function as follows:
1. Signal Change
a. When using the signal change function, it is recommended to use a static test pattern.
Every second the STIX-AF will check for changes in the video signal such as resolution,
color space, refresh rate, and RGB Triplet values. If any of the video frame values have
changed, the value will increase by 1.
b. In the event the HDMI source device disconnects; if the signal remains unchanged, when
reconnected, the value will remain unchanged.
c. The Signal Change field will count to 999, any new signal changes will roll over the count
to 001.
2. Sync Loss
a. The number of times the TMDS/FRL negotiation has been lost or disconnected, counting
begins after initial video signal connection.
b. The Sync Loss field will count to 999, any new signal changes will roll over the count to
001.
c. Sync Loss can measure up to 65,535 instances when connected directly to the control
port via serial.
3. Time
a. The total uptime of the unit.
b. The Time field will count to 99h 59m 59s. Additional uptime will roll over the uptime to 00h
00m 01s.
4. Resetting the Signal Monitor screen
a. While the Signal Monitor screen is open, press and hold the function button for 2 seconds.
b. Signal Monitor settings are volatile and will reset after a power cycle.
Screen Saver
The blank (black) screen saver will appear after 5 minutes of inactivity. During this state the STIX-AF is
operational, and serial data may be sent to and received from the unit. Users may open the Home Screen
at any time by pressing the function button. Signal changes or changes in the HDMI sync will cause the
Home Screen to open as a response.

USER SENT:
GET CRC VAL<cr>
ECHO RECEIVED:
CRC Value {integer}<cr>
The CRC Value will calculate the checksum of the video signal, including resolution, color space, refresh
rate, and RGB Triplet values. Any change in video signal, including moving video, will cause the CRC Value
to change. It is recommended to use a static test pattern when testing for Signal Change.
Sync Loss Testing
EVENT:
TMDS/FRL connection has been lost
ECHO RECEIVED:
SYNC LOSS {32 bit Integer} <cr>
If the HDMI connection is dropped between the HDMI Output and the STIX-AF, the STIX-AF will echo the
number of instances the connection has been lost. The Sync Loss counter begins after the first HDMI
connection is established and will continue to count until the unit is either reset or power-cycled.
USER SENT:
SET INx TMDS ON/OFF<cr>
ECHO RECEIVED:
INx TMDS ON/OFF<cr>
The HDMI Inputs operating state can be manually toggled using the command above. When an active
video signal is present, this allows the user to simulate a Sync Loss.
Audio Loss Testing
EVENT:
Audio format has changed or connection has been lost
ECHO RECEIVED:
AUDIO LOSS {32 bit Integer} <cr>
If the audio format is changed or the connection is dropped between the HDMI Output and the STIX-AF,
the STIX-AF will echo the number of instances the connection has been lost. The Audio Loss counter
begins after the first HDMI connection is established and will continue to count until the unit is either reset
or power-cycled.
PRBS Pass Testing
While an HDMI connection is established with the STIX-GF, the STIX-AF will check the PBRS in intervals. A
PASS result indicates that the STIX-AF detected no bit errors during the test cycle, confirming error-free
transmission over the measured interval. The PBRS Pass counter begins after the first HDMI connection is
established and will continue to count until the unit is either reset or power-cycled.
