SL-889 HDMI 2.1 Cat-3 Cable EMI Tester User Guide 1. Overview The SL-889 HDMI 2.1 Cat-3 Cable EMI Tester is designed for radiated emissions testing of HDMI 2.1 Ultra High Speed ® cables and is compliant to the latest High Definition Multimedia Interface (HDMI ) 2.1 specifications.
Figure 1.3 shows the internal and external signal path of the SL-889. An internal Video Generator generates an ITU-R BT-1729 test pattern which is fed to an HDMI transmitter. When an external HDMI cable DUT is connected, the Tx will begin transmitting a HDMI 2.1 Video/Audio data stream to the built-in HDMI receiver.
Standard test operations are available for: • HDMI 2.1 Cat-3 Cables HDMI 2.1 Video Resolution Support The SL-889 includes support for TMDS and FRL signalling: • 6 TMDS Freqencies supported with 4 Video Resolutions • 2 FRL Frequencies with 2160p60 Video Resolution...
1.5.2. 2M Golden Test HDMI Cat-3 Cable The included 2M cable has been developed for specific use with the SL-889. It has been shown to have superior RF suppression. It should be kept as a test reference cable and can be used to calibrate your SL-889 to different RF chambers.
The SL-889 generates fixed stimulus to an HDMI 2.1 Category 3 Cable so the DUT cable’s EMC Emission performance can be measured. The SL-889 does not go through HDMI 2.1 FRL Link Training, and does not adjust the TX signal in response to the RX’s measured error rate.
2.1. Note: As the test is intended to measure only the radiated emissions of the DUT cable, the cable from HDMI OUT2 should be disconnected from the SL-889, and the 4K Monitor should be unplugged from AC power prior to making any EMI measurement scans.
SL-889 HDMI 2.1 Cat-3 Cable EMI Tester User Guide Setting up Connections – Normal Operation Connecting the DUT cable to the SL-889: • When performing EMI RF scans, the DUT cable should be connected from HDMI OUT1 to HDMI IN1 as shown Figure 2.2Figure 2.2.
(C0-C15). The second line will display “Searching …” if an HDMI cable has not yet been connected from HDMI OUT1 to HDMI IN1. Figure 2.4. SL-889 Operation: C0 Resolution, V1.00 Firmware, No HDMI Cable Attached 3. Rotate the knob to select the resolution to be tested.
(ex: “TMDS 185 MHz”) when a link has been successfully connected. The unit is now ready for EMI scans to be taken. Figure 2.7. SL-889 Operation: C4 Resolution, TMDS 185 MHz link, HDMI Cable Attached Attach an optional HDMI monitor to HDMI OUT2 to display the ITU BT1729 test pattern.
2.6.1. CISPR Chamber Set Up – Cable Placement For CISPR compliance it is assumed that the SL-889 would be pushed to the front of the table facing the antenna with the DUT cable draped down the front as shown in (Figure 2.9. CISPR recommended DUT cable placement inside chamber), and tied in a loose bow to prevent it from hitting the floor.
HDMI 2.1 EMI Measurement The SL-889 provides a complete transmit and receive solution of a compliant HDMI 2.1 signal output in a low noise shielded enclosure. It can be used to measure the radiated emission levels of HDMI cables by taking RF level scans in a calibrated EMI chamber.
EMI Limits and Testing EMI or electromagnetic interference is the measure of the radiated RF energy that a device puts out. The SL-889 makes measuring the amount of RF energy an HDMI cable emits easy, by providing a calibrated HDMI signal. Maximum allowable EMI limits vary from country to country, and this tool was developed to help standardize the rf emission measurement of cables regardless of country standard.
Software Package. (Figure A.1). The *.zip package contains firmware installation files. Note: To check the firmware version installed on the SL-889, turn the selector knob to “C0”. If the version matches with the LCD displayed value (Figure A.2), there is no need to update. The version number is also displayed on the C0 screen monitor output.
