S/N005 phase-noise measurement at 10 MHz
added by Anders Wallin on 2017-08-18 06:38:16.076162
Phase-noise measurements show a flat spur-free phase-noise and AM-noise
floor of -162 dBc/Hz at >100 Hz offset from a 10 MHz carrier.
Measurements at 5 MHz to follow.
See wiki for results.
S/N005 assembled and tested
added by Anders Wallin on 2017-08-16 13:29:13.497624
Amplifier S/N 005 was assembled and tested, housing PDA2017.07 and
Initial phase-noise tests show good performance, similar to the previous
generation of the board.
The new PDA2017.07 design using IDT5PB1108 has very fast rise-time (to
be measured), possibly a quite low output-impedance (to be fixed?) and a
preliminary channel-to-channel output skew of max 250 ps.
