Hi,
In a previous answer to "As for Safe-State Transiton of HMC1119", the glitch was about 0.64dB. I obtained an HMC1119 evaluation board and measured it, and found a drop in level of about 12dB. This was when the ATT was changed from 16dB to 15dB. The RF signal was 300MHz. Is there anything I should be careful of when measuring?

Best regards,
Akira
