Hi Samuel,
Thanks
The following worked
ftp = FTP(host="192.168.255.69")
However, if I want the transfer to be in binary mode then it won't work

[julia-users] Re: unable to connect to FTP using IP address
Hi Samuel,
Here is how it is done in matlab
% connect to ftp
f = ftp(host, username, password)
mget(f,'dataOnFTP.bin')
% read data from file
readData = fopen('dataOnFTP.bin', 'r', 'ieee-le')
%delete file from server
delete(f, 'dataOnFTP.bin');
Here one thing not included is I would like to find the latest file from
FTP server because there might be similar names with different suffix.
Thanks

[julia-users] Re: FFT, PSD and Windowing functions
Hi Islam,
Thanks again for your inputs,
the first method worked, as you mentioned it was missing dot to do element
wise multiplication.
Here is what it looks like
pow_fs = (((2^(adc_bits-1))-1))^2 / 2
fb= fb.*hanning(length(fb))
When I tried the weltch function, it actually has two sets of data as shown
below, how do you split data to plot and manipulate the array?
Here is the command I used, periodogram(fb*; onesided=eltype(fb)<:Real*,
*nfft=nextfastfft(length(fb)*, *fs=150*, *window=hanning*)*ΒΆ*
<http://dspjl.readthedocs.io/en/latest/periodograms.html#periodogram>
data collected
Thanks
Yared

[julia-users] Re: FFT, PSD and Windowing functions
Hi Islam,
Thanks for your input
I was able to find all windowing functions; however, there is nothing
about PSD ( power spectral density). In python and matlab, there is
function pwelch which does both windowing and FFT and wondering if there is
the same function in Julia.
Here is simple trial I had but it is complaining about type mismatch
fb= fb[:]*hamming(length(fb))
fb = fft(fb) # take FFT of signal
LoadError: MethodError: `*` has no method matching
*(::Array{Complex{Float64},1}, ::Array{Float64,1})
Closest candidates are:
*(::Any, ::Any, !Matched::Any, !Matched::Any...)
*{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},S}(!Matched::Union{DenseArray{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},2},SubArray{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},2,A<:DenseArray{T,N},I<:Tuple{Vararg{Union{Colon,Int64,Range{Int64,LD}},

Thanks for quick response, it works in most cases but when the number is float, parse has problem as shown below How about when the number has decimal points for example exString = "Exact number 390 \n Exact qty: +200.5 people \n Starting number: 5 now 16.5A_C" srchStr ="Exact qty:" search(exString, srchStr) ans = exString[search(exString, srchStr)[end]+1:end] |> strip |> split value1= parse(string,ans[1]) Thanks Yared On Monday, July 18, 2016 at 1:31:16 PM UTC-5, Yared Melese wrote: > Hello > > I was trying to parse a number from string as shown below.

[julia-users] Julia String Manipulation
Hello I was trying to parse a number from string as shown below. Would you please let me know if there is easy way to get the number after a specific string ? please note that the string can be variable(different) goal is to specify search string and put out exact number with out any text before and after the number. The current program shown below has two faults 1. on line 10, I have to manually enter starting word but cannot put a variable as shown below c = match(r"$srchStr[\w|\w %s%f%f|.|:|+]*", b[srchInd]) 2. I have to only get a number, that means anything in front and behind that number should be stripped off exString = "Exact number 390 \n Exact qty: +200 people \n Starting number: 5 now 16.5A_C" srchStr ="Exact qty:" b= split(exString,"\n") # put each line to an array form #find index of excact string match for i in 1:length(b) if contains(b[i], srchStr) == true srchInd = i end end c = match(r"$srchStr[\w|\w %s%f%f|.|:|+]*", b[srchInd]) d=replace(c.match, srchStr,"") print(d)
Re: [julia-users] Re: testing intrument Automation
Thanks for your quick response
I have different commands that I want to control instruments via GPIB
commands, It will be okay if I can import NI visa and build different logic
in automating instruments.
Here is a simple Python command I send to setup spectrum analyzer. I am a
beginner and I would like to learn and stick with one language and Julia
seems to be interesting to me
import visa
import numpy as np
class MXA_ACP:
def __init__(self,gpib_address="GPIB0::18",hw = 1, route = "A"):
rm = visa.ResourceManager()
self.handle = rm.open_resource('{}::INSTR'.format(gpib_address))
#self.handle=
visa.instrument('TCPIP0::{}::INSTR'.format(TCPIP_Address))
def ACP_set(self,BW,freq,numCarr,spacing):
self.handle.write('system:preset')
self.handle.write('CONFigure:ACPower')
self.handle.write('CONFigure:ACPower:NDEFault')
self.handle.write('INST:SEL LTE')
# set standard based on BW
if BW ==5:
self.handle.write('SENSe:RADio:STANdard:PRESet B5M')
elif BW == 10:
self.handle.write('SENSe:RADio:STANdard:PRESet B10M')
elif BW == 20:
self.handle.write('SENSe:RADio:STANdard:PRESet B20M')
self.handle.write('ACP:carr:coun {}'.format(numCarr)) #set number of
carriers
self.handle.write('ACP:carrier:RCFR {} MHz'.format(freq))#set Freq
self.handle.write('ACP:carr1:list:width {} MHz'.format(spacing)) #
set carrier spacing
self.handle.write('Corr:nois:flo ON') # noise floor extention
self.handle.write(':power:RF:range:optimize immediate')
self.handle.write('ACP:aver:coun 50') # averaging
self.handle.write('*WAI') # wait for averaging to finish
acp = np.fromstring(self.handle.ask('read:ACP?'), sep=',')
acp_3rd_upper = acp[4]
acp_3rd_lower= acp[6]
acp_5th_upper= acp[8]
acp_5th_lower= acp[10]
print acp_3rd_upper
print acp_3rd_lower
print acp_5th_upper
print acp_5th_lower
return acp_3rd_upper, acp_3rd_lower,acp_5th_upper

Can Julia be used as instrument test Automation? Send commands via GPIB to different instruments If so is there Visa library for it? Thanks Yared
