Can I use P7380SMA for HDMI source measurements?
P7380SMA has a better response than P7350SMA and P7330. But it cannot be used with the HDMI solution with the current test setup due to the 3.1 V DC offset in the HDMI signals. The P7380SMA can accommodate up to ± 2.5V as common mode voltage. However, with some changes customers can use the following probing solution. The user may need a DC blocking circuits to bring the signals to the operating range of the P7380SMA.
NOTE: this is applicable to testing under CTS1.0, 1.2,and 1.2. CTS 1.3 changes probe recommendations.
