PEIS params : duration #17

Closed Cdriko closed 2 years ago

Cdriko commented 2 years ago

Hello I don't understand the "duration" parameter of a PEIS technique.

It doesn't appears in EC-lab development package doc : In this doc there is

vs_initial vs_final initial_voltage_step final_voltage_step duration_step step_number record_every_dT record_every_dI final_frequency initial_frequency sweep Amplitude_Voltage Frequency_number Average_N_times Correction Wait_for_steady

Can you explain how this parameter works ? It seems to be a timeout like, but it's difficult to estimate the duration of this kind of technique.

Thanks

I trys following settings (inxml in my soft) but a can't get more than 4 frequency result, despite that I set 10 points by decade.

<amplitude_voltage>0.1</amplitude_voltage>
<initial_frequency>1000000</initial_frequency>
<final_frequency>0.1</final_frequency>
<time_interval>1.5</time_interval>
<voltage>0</voltage>
<frequency_number>10</frequency_number>
<average_n_times>2</average_n_times>
<duration>1000</duration>

The duration parameter maps to the Duration_step PEIS parameter (Sec. 7.11.2 in the EC-Lab Development Package User's Guide Version 6.00 – April 2017) which has the description of "Step duration in seconds". Does that help answer the question?
