Intro: (top)

see ips info page for a description of how the data is taken and processed.

Interplanetary Scintillation (ips) test measurements were done aug2018. The setup was:

project a3285, source code x101/projects/ips/
327,lbw,sbw,cband receivers were used.
On/Off position switching (with 3min on, 3 min Off) using continuum sources was used to measure the ips.
The mock spectrometer was used to record the data. The setups (by receiver) were:

rcvr	FreqBands (MHz)	Bandwidth/band (MHz)	#FreqChannels	sampleTm (ms)	notes
327	327	53.	1024	1.9968
lbw	1160,1240,1400,1480,1620,1700	80	2048	1.9968 0.9984	switched to 1ms to stop radar ipp aliasing
sbw	2740,2820,2900,2980	80	2048	1.9968	180821 2290 replaced with 2740
sbh	3120,3200,3280,3340,3420,3500,3580	80	2048	1.9968
cb	4280,4440,4600,4760,4920	160	4096	1.9968

Notes:

180824.

3C237 cband. 4920 band.. 2nd lo was failing 12 db too little power..
3C327 lbw, 1st pattern, punta salinas not in mode A.. 2nd pattern then moved to modeA
