<GitHub-m-labs> [artiq] gkasprow commented on issue #1080: I checked with Ohmmeter before the HMC starts and resistance is higher than a few kOhms so it means that termination did not start calibration yet. After the HMC starts, I measure 40Ohm/70Ohm on CLK2 and 98/96Ohm on CLK1. Since the multimeter uses integrating converter, it does not care about 1Vpp RF signal on it. Difference between measurements with changed leads is
<GitHub-m-labs> [artiq] gkasprow commented on issue #1080: So it looks like CLK2 has some troubles with impedance calibration... I will reset the HMC and measure R again. https://github.com/m-labs/artiq/issues/1080#issuecomment-408094486

But the resistance I mesure acrross the FPGA input on CLK input does not change when I keep tht HMC in reset state. https://github.com/m-labs/artiq/issues/1080#issuecomment-408097352
