Single channel trace
One channel, one sweep. The gate traces on top show each gating particle moving between its resting (low) and activated (high) position, time-aligned with the current below.
| # | Test V (mV) | ΔI (pA) |
|---|
Multiple sweeps
The same channel, repeated trials at the same test potential — trial-to-trial variability in latency, opening count and duration. As on a real rig, one sweep is acquired every 500 ms and each new sweep is drawn below the previous one. Right-click any trace to drop a marker and log its (voltage, current) into the table.
| Sweep | First latency (ms) | # openings | Total open time (ms) | Po |
|---|
| # | Sweep | Time (ms) | Voltage (mV) | I (pA) |
|---|
Ensemble average
Average many independent channels (or repeated sweeps) and the noisy single-channel flickers become the smooth macroscopic current students recognize from whole-cell recordings. Sweeps are acquired one every 500 ms and overlaid; when the last one arrives the average is computed and drawn on top. Right-click the bold average trace to log its (voltage, current) into the table.
| # | Time (ms) | Voltage (mV) | I (pA) |

Dwell-time histograms
Runs 200 pulses one at a time, like watching an oscilloscope sweep — most informative for the Kᵥ channel, whose non-inactivating flicker gives many open/closed events per pulse. Every 5th pulse, the closed- and open-time histograms below update with all events collected so far (first latency and any dwell still in progress at pulse end are excluded, to avoid bias).
