PROGRAM: Temperature Dependent I-V Measurement
4+
5+
PURPOSE: Automates Voltage vs. Temperature characterization by integrating
6+
a Lakeshore 350 and a Keithley 2400.
7+
8+
DESCRIPTION: This script automates Voltage vs. Temperature (V-T)
9+
characterization by integrating a Lakeshore 350 Temperature
10+
Controller and a Keithley 2400 SourceMeter. The script sets a
11+
target temperature, waits for it to stabilize, and then
12+
performs a full I-V sweep at that temperature, repeating the
13+
process for a user-defined range of temperatures.

PROGRAM: Keithley 6517B I-V Sweep Measurement
4+
5+
PURPOSE: Perform a voltage sweep and measure current to generate an I-V
6+
curve using a Keithley 6517B.
7+
8+
DESCRIPTION: This script automates an I-V sweep measurement using a Keithley
9+
6517B electrometer. It prompts the user for sweep parameters
10+
(start/stop voltage, steps, delay), performs a zero-check
11+
correction, executes the voltage sweep while measuring current,
12+
saves the data to a CSV file, and displays a plot of the
13+
resulting I-V curve.

PROGRAM: Integrated R-T Measurement Control
4+
5+
PURPOSE: Automate and log a Resistance vs. Temperature (R-T) measurement
6+
using a command-line interface.
7+
8+
DESCRIPTION: This script provides a command-line framework for automating an
9+
R-T characterization by integrating a Lakeshore 350 Temperature
10+
Controller and a Keithley 6517B Electrometer. The program
11+
prompts the user for all experiment parameters (temperature
12+
range, ramp rate, source voltage), performs a robust temperature
13+
stabilization, and then executes a linear temperature ramp.
14+
During the ramp, it continuously measures resistance and logs
15+
all data to a CSV file, while providing a live plot for visual
16+
feedback. The script ensures a safe shutdown of all instruments
17+
upon completion, error, or user interruption.

PROGRAM: Pyroelectric Measurement GUI
12+
13+
PURPOSE: Perform a pyroelectric current measurement with two-stage
14+
temperature ramp control.
15+
16+
DESCRIPTION: This program provides a graphical user interface (GUI) for
17+
automating a pyroelectric current measurement. It integrates a
18+
Lakeshore 350 for temperature control and a Keithley 6517B for
19+
sensitive current measurement. The experiment involves a
20+
two-stage process: first stabilizing at a start temperature,
21+
then ramping to an end temperature while logging data. The GUI
22+
features live plotting and a detailed console.

Description:
12-
This is a simple, general-purpose script to verify connections with any
13-
instrument recognized by VISA (e.g., via GPIB, USB, Ethernet). It automatically
14-
scans for all connected devices and attempts to query each one for its
15-
identification string (*IDN?).
16-
17-
The script will print the ID for each responsive instrument and report an
18-
error for any that are unreachable, making it a quick diagnostic tool for
19-
debugging instrument control setups.
20-
21-
Dependencies:
22-
- pyvisa: A Python package for instrument control.
23-
- A VISA backend must be installed (e.g., NI-VISA, Keysight VISA).
24-
25-
Usage:
26-
Run the script directly from your terminal. No code modification is needed,
27-
as it will automatically find and test all connected instruments.
