* Investigation of baseband ripples in DASH345 (ASTE-220) [#n52935ac]

** Notes [#f6f5b534]
- To 伊藤さま (from 鎌ざき)
-- synthe_ctlのamplitude設定に上限値はありません。+23dBも設定できます。
-- EP Aqrの指示書を用意しました。

- ''Allan variance measurement test''
-- Receiver PC in RX cabin aste-rec window shows to aste-mx1 with VNC.
-- Measurement Allan variance was succeed twice.
-- &ref(./Allan-DASH345-ch1-100-5000.png,,30%);
-- In third time, LabVIEW window stopped and I need close the window and end the VI program. 
-- &ref(./Allan-window-stop-20170712.png,,30%);
-- After this, WHSF analogue backend (192.168.11.164, 165) replied by ping-command, but whsf_rsky command was stopped at just after showing "Connected to: IF module".
-- I need "whsf_ae_sw REBOOT" command.
-- Allan variance measurement will retry tomorrow.
