Hello,<br> USB recommendations are FAT32 configuration, 16GB or less for optimal performance.<br> Additionally, if you are upgrading from a firmware version earlier than 1.7.10, use the<strong> Downgrade to older</strong> option from the front panel or use the downgrade remote commands. When upgrading from a firmware version earlier than 1.7.10, system messages will display the firmware version as 1.7.1. This is a cosmetic issue and does not affect instrument performance.<br> I would recommend retrying this procedure with the smaller USB stick, ensure it is in FAT32 formatting, and use the firmware version 1.7.12 provided below as this is the most current firmware version for the DMM7510.<br> Follow the instructions starting on page 3 in the release notes found at the same link.<br> <br> <a href="https://www.tek.com/en/support/software/firmware/model-dmm7510-firmware-revision-1712-and-release-notes">Model DMM7510 Firmware Revision 1.7.12 and Release Notes | Tektronix</a><br> <br> Please let me know if this resolves your issue!<br> &#160;

<p>Hello,</p> <p>What instrument model number and accessories are you using? What settings do you have enabled for your test? What range are you using for measurements and what is your expected value(s)?</p>

Michel,<br> Can you provide a screenshot or picture of the 2450's screen showing these question marks on the info/manage screen?

Paul,<br> You will only be able to use either the front or rear terminals. You cannot use both front panel and rear panel terminals simultaneously.

Hello,<br> The recommended cables and accessories for the 2657A can be found on the datasheet for the unit found below. Also, the cables and accessories that the HV-CA-554 can be used with can be found on the HV-CA-554 manual also provided below.<br> <font face="Calibri, sans-serif"><span style="font-size:11pt;">We only recommend HV Triax for these voltages. We do have Triax-BNC adaptor that is rated for 1300V, but we do not recommend because most BNC cables and connectors are only rated to 300-500V. Since the 2657A goes beyond the capabilities of </span><span style="font-size:14.6667px;">most</span><span style="font-size:11pt;">&#160;BNC cables and connectors, I am unable to recommend using a TRX to BNC adaptor with this unit.</span></font><br> <br> <a href="https://www.tek.com/en/datasheet/2657a-high-power-system-sourcemeter-smu-instrument">2657A High Power System SourceMeter SMU Instrument | Tektronix</a><br> <a href="https://www.tek.com/en/manual/model-hv-ca-554-high-voltage-triaxial-cable-inform">Model HV-CA-554 High-Voltage Triaxial Cable Information | Tektronix</a>

Hello,<br> Please run the altered code below and let me know if this performs how you were expecting it to. <pre>import pyvisa as visa rm = visa.ResourceManager('@py') #print(rm.list_resources()) address1 = &quot;TCPIP0::192.168.0.45::inst0::INSTR&quot; dmm = rm.open_resource(address1) dmm.write('*RST') dmm.write(':TRACe:MAKE &quot;voltDigBuffer&quot;, 10000') dmm.write(':DIG:FUNC &quot;VOLTage&quot;') dmm.write(':SENS:DIG:COUN 100') dmm.write(':INIT') print(dmm.query(':TRAC:DATA? 95, 100, &quot;voltDigBuffer&quot;')) dmm.close() rm.close()</pre>

Hello,<br> Can you give some more detail for your question &quot;How can I query data from buffer like .xls file?&quot;? Thanks in advance!

Hello Justin.<br> In step 3, the procedure has you configure in 2-wire mode, not 4-wire. Is there a procedure you are using in your version of the manual that includes a 4-wire mode adjustment for the high(100 MOhm) range?<br> Here is the version I am using:<br> <a href="https://www.tek.com/en/tektronix-and-keithley-digital-multimeter/2110-series-5%C2%BD-digit-dual-display-usb-multimeter-manu">Model 2110 5 1/2 Digit Digital Multimeter Calibration Manual | Tektronix</a>

Hello,<br> What I would recommend for having a greater time interval between your measurements is to take a look at output delay in the manual below, as well as source delay.<br> Output delay I would read through how that function works and see if you want to utilize this function.<br> For source delay, I would recommend setting this to the max interval (99 s.) so there is a larger time difference between each of your measurements, meaning it will take longer between measurements and increase the time of your test.<br> <br> A different way you could achieve the 15-minute window between measurements, or a time frame around that mark, is to utilize external triggering.<br> <br> See page 3.5 AND ON for all of this information for the SDM (Source Delay Measure) process.<br> <a href="https://www.tek.com/en/tektronix-and-keithley-dc-power-supplies/keithley-2280s-series-manual/series-2280-precision">Series 2280 Precision Measurement DC Power Supplies Reference Manual | Tektronix</a>
