The 2600-PCT-2B contains two SourceMeter models:  2651A and 2636B.  Many (not all) of the specs you seek will be in the datasheet for the individual SMUs.  I encourage you to contact your closest sales office and discuss your application and concerns.

Is the sample in any sort of shielded test fixture?<br> <br> Double check your connections.&#160; Are you making use of meter-connect to connect LO of Amps meter to the LO of the V-Source?<br> <br> When was your electrometer last calibrated? Perhaps try with an axial leaded high ohms device as practice and to raise confidence in function of the instrument.<br> <br> There are many instructional videos on the 6517B web page.<br> Try this one:&#160;&#160;https://www.tek.com/en/video/how-to/how-to-make-a-resistance-measurement-using-the-model-6517b-electrometer-with-auto-and-manual-modes

Here is some Python code that might more in line with what you are trying to do.<br> I will upload an image of the outputs I get.&#160; I have been feeding a 500Hz sine wave to the DMM7510. <pre class="linenums prettyprint">debug = 1 NUM_SAMPLES = 100 my_instr.write('*RST') my_instr.write(':TRACe:MAKE &quot;voltDigBuffer&quot;,' + str(NUM_SAMPLES)) my_instr.write(':DIG:FUNC &quot;VOLTage&quot;') my_instr.write(':SENS:DIG:VOLT:INP AUTO') my_instr.write(':SENS:DIG:VOLT:RANG 10') my_instr.write(':SENS:DIG:VOLT:SRATE 5000') &#160; #5KHz sample rate my_instr.write(':SENS:DIG:VOLT:APER AUTO') my_instr.write(':SENS:DIG:COUN ' + str(NUM_SAMPLES)) my_instr.write(':TRAC:POIN ' + str(NUM_SAMPLES)) my_instr.write(':TRAC:CLE') my_instr.write(':TRAC:TRIG:DIG &quot;voltDigBuffer&quot;') # wait for done before asking for the data time.sleep(1) &#160;#pause before asking for data if debug == 1: &#160; &#160; my_instr.write(':TRAC:DATA? 95, 100, &quot;voltDigBuffer&quot;, REL, READ') &#160; &#160; print(&quot;****** response to last five points query *************&quot;) &#160; &#160; print(my_instr.read()) #split, parse, etc. &quot;&quot;&quot; raw_data will be comma delimted string of&#160; timestamp, reading, timestamp, reading,... etc. &quot;&quot;&quot; #ask for all the data #TODO: &#160;adjust for NUM_SAMPLES raw_data = my_instr.query(':TRAC:DATA? 1, 100, &quot;voltDigBuffer&quot;, REL, READ') raw_data_array = raw_data.split(',') timestamps = [] Digitized_V = [] # use step of 2 because there are two elements per reading for i in range(0, len(raw_data_array), 2): &#160; &#160; if len(raw_data_array[i]) &gt; 0: &#160; &#160; &#160; &#160; timestamps.append(float(raw_data_array[i])) &#160; &#160; &#160; &#160; Digitized_V.append(float(raw_data_array[i+1])) if debug == 1: &#160; &#160; print(&quot;******* Timestamps *******************&quot;) &#160; &#160; &#160; &#160; &#160; &#160; print(timestamps) &#160; &#160; print(&quot;******** Voltage ******************&quot;) &#160; &#160; print(Digitized_V) &#160; &#160; print(&quot;**************************&quot;) &#160; &#160; print() #graph it plt.autoscale(True, True, True) #plt.axis([0, 0.2, 0, 50e-6]) plt.plot(timestamps, Digitized_V, 'c--') plt.show() </pre>

In general, when the command you send ends with the question mark (a query type command), you should immediately follow with a read to pull the response to the query command off the output queue.<br> <br> You are sending more than one command in a row.&#160; The first time you read, you will get the response from the first query command, not from the most recent.<br> <br> I'll attach a screen image of your code and the outputs but using a read after each query command.

Can you successfully ping the IP address of the instrument?<br> What's the IP address of the computer from which you are trying this?<br> <br> From PuTTY, is straightforward to get a Telnet session on port 23.&#160; See attached document.

The&#160;TP3005DM is not a model I recognize. &#160;A google search shows it as made by company “TekPower” not Tektronix.<br> <br> Consider our various single channel models from the 2200 series.<br> https://www.tek.com/en/products/keithley/dc-power-supplies/2200-dc-power-supply<br> &#160;

Are you moving the scope card between the two systems?&#160; Or do they both have a scope card and just the one running KITE 9.1 is not working?<br> <br> If you are attempting to move the card between the two systems, it will not work.&#160; The expected cards of the configuration is not designed to be modified in the field.&#160; So if the KITE 9.1 system never had a scope card, it will not be accepted by the KCON config.<br> <br> Please clarify.

Ayoub,<br> <br> Your post seem off topic, so I created a different thread for managing 4200A-CVIV switch.&#160;&#160;<br> https://my.tek.com/tektalk/semi-para-analyzer/7654133b-38da-ed11-a81c-00224809317b<br> <br> Andrea<br> &#160;

In Clarius software, be sure to make use of an Action to route the SMU or CVU to the output.<br> Execute the Action before you attempt to perform the SMU or CVU measurement.<br> In the Select ribbon, search for a project using &quot;CVIV&quot; as the search term.<br> Those projects will include the Action steps for configuring the CVIV prior to a measurement.
