I looked through that code (I don't have a convenient system to build/run it on)-- it appears to download either 1200 or 250000 bytes. My problem is when downloading 8244+n*64 only -- 250000 is not an issue in that.

My problem arose when I was specifically downloading different lengths in the range below 30000; it arose from old habits of being frugal with memory. I changed my own code to download 8000 byte chunks, but I guess I could just download a single 30000 byte block and truncate it.

In the end, I don't know if this ia Rigol or a pyvisa bug.

p.s. I updated my example above to select the USB instrument more easily.

It looks like you're trying to use a USB connection?

I don't know if it will have any effect.  But, you could try changing the OS low level receive buffer size.  The default size for a LAN connection would be different than a USB connection.

@PeDre - thanks for checking. I see it works for you at 8244. What is that program you used ?

When I run my pyvisa program with different values for chunk_size:
DS1054Z = GPIB.open_resource([_ for _ in GPIB_Resources if re.search('^USB.*:DS.*INSTR$', _)][0],chunk_size=3000)

it doesn't appear to fail as often, but there are definite slow downs at some points (watch the results scroll by) -- they appear to be at 64-count intervals. In my case, starting at 8200:
for NPOINTS in range(8200,30100):# fails at 8244 first

gives a slowdown (but not a fail) at 8226.

Yes, USB. I have tried with the LAN with longer lengths with no problems. I haven't tried this code over the LAN -- will do (it appears you have to reboot the scope to switch from USB to LAN).

-- update: - I can't get my pyvisa to work over the LAN. Anyone know the magic resource name ? IP = 10.1.0.54, port = 5555
Code: [Select]
GPIB = visa.ResourceManager()
DS1054Z = GPIB.open_resource('TCPIP0::10.1.0.54::5555::INSTR')
print("DS1054Z:", DS1054Z.query("*IDN?"))
fails

Don't know how to change the OS buffer size. There is a chunk_size option in pyvisa which has an impact -- it moves the starting point of the issue around, but doesn't eliminate the issue.

Hi all,

for me the password login rigollan/111111 or test/111111 never worked, and since the headline post of this thread states that this problem should be gone with the current firmware version, I updated and tried again; no success. But this finally worked for me:

  • Connect to the scope via http://[IP-Address]
  • Select "Security"
  • Enter as old password: 111111
  • Enter as new password again: 111111 (twice)
  • Confirm --> Success message
  • log in with any username with four or less letters, pw 111111 --> Works!

So I used as username test, blah, 1234, a - all worked. 12345 or rigollan or rigolan did not work.

No idea why my scope behaves differently as others, but from the forum I find others that used test and blah also successfully.

Whatever - /me is happy now.

Cheers

Hauke

Hello,
I posted sometimes:

With the last Version 00.04.04.03.05 the login is now working with:
username: rigolan
password: 111111

Hi Wolfgang,

sorry to say: But not for me. It is as I write: any four letter (or shorter) username works, anything 5 digits plus: No success.

Or are we talking about different logins? I refer to accessing http://[IP of the scope]/, and then hitting "Network settings". Where do you refer to?

Cheers

Hauke
