To make it easier to recall a specific Bode setup, the firmware saves the instrument configurations in the data file for the Bode plot.

The process is simple: Configure the scope and generator for your device/circuit to test, run the Bode plot, save the data, and then recall it when you need to re-run that specific setup.

Here are the steps using a SIGLENT SDS1204X-E, but the process is very similar for all of the applicable models:

1. Open the Bode II application by pressing Utility (Analysis on non-XE models):

2. Configure the sweep parameters. For this example, we are going to simply change the end frequency to 200 kHz and the number of points to 200

Press “Set Sweep”:

Here, the default end frequency is 10 kHz and the points are 50:

Let’s change them:

3. Run the setup once. It doesn’t have to complete, but it does have to start:

4. Now, you can save the data and the setup in one CSV file. Here, we save it to an external USB memory device:

5. When you want to recall, insert the USB memory device or recall from the internal memory. Open the Bode II application on the scope, click on Data, press Recall, and select the file of interest :

Make sure that the settings are correct before testing sensitive devices:

For this note, we will be using the SIGLENT CP4020 current probe and the SDS1104X-E oscilloscope as well as an SPD1168X power supply.

1. Let’s check the noise floor of the scope. The SDS1104X-E has a 500 uV/division minimum scale. The channel noise (with no input connection/CH1 open) is approximately 1 division (500 uV p-p):

2. Now, let’s connect the probe, turn it on, and switch the gain to the most sensitive setting. In this case, 50 mV/A:

The noise on the 500 uV/div vertical scale is dominating the screen.. so we can adjust the scale until we get some headroom… 5 mV/div is better..

10 mV/div even more so.

3. Now, let’s enable averaging. For continuous (DC) outputs or repeated waveforms, averaging can be used to minimize random noise:

4. We can also use the Zero function of the probe to minimize the DC offset of the measurement. Now, our open-circuit voltage average is near 0 V.

5. Now, we can set the Units of Channel 1 to Amps (as we are measuring current) by pressing 1 to open the channel options menu. Set units to A and then select a custom scale factor so that the proper readings are displayed on the oscilloscope.

The probe is set to the 50 mV/A gain setting.

The scope always measures Volts.. so we would like to get this into Amps-per-Volt (A/V) so that we are converting the input signal (in Volts) to current (Amps)

The inverse of the probe gain is 1/(50 mV/A) = 0.02 A/mV * 1000 mV/V = 20 A/V

So, a 1 A current will provide a voltage at the scope of 50 mV/A * 1 A

6. Now, test the setup by sourcing a simple DC current with a power supply and a suitable wire to carry the current:

I enabled a mean measurement which shows the value of the average signal input:

The final estimate is that the CP4020 and XE scope have a low current measurement of approximately 50 mA.

Many instruments support communication via sockets (port 5025) and telnet (port 5024) but the port numbers cannot be changed.

If you use VISA, you can implement LAN via TCP/IP, which does not need a port number.

Here is a listing of current SIGLENT instruments with Socket and Telnet Support.
