Bench & instruments

Supported instruments

The instrument types TestFlow drives, the vendors covered for each, and what happens with hardware that has no standard command set.

Instrument vendors TestFlow drives over VISA and SCPI: Keysight, Tektronix, Rohde & Schwarz, NI, Keithley, Agilent, Anritsu, Siglent, Chroma, Fluke, Yokogawa, Kikusui, TDK-Lambda, ESPEC, Watlow, Pickering, Copper Mountain, inTEST, Thermonics, and Microchip. — Vendors TestFlow drives over VISA. The catalog grows continuously.

By category

The instrument catalog's category rail and card grid, showing the counts per category and cards for the Core 360 Rack, Oscilloscope, Multimeter, Power Analyzer, Phase Noise, Power Supply, Source Meter, Dynamic Load, Function Generator, Spectrum Analyzer, Vector Signal Generator and VNA. — The same list, in the product. The counts on the rail are the ones in the table below.

What an action catalog is

A power supply step showing three named actions: Select_Channel, Set_Current and Turn_On_CH1, with their parameters. — What you pick: named actions on the canvas.

Generated Python sending INSTrument:SELect CH1 with the comment Select_Channel and SOURce:CURRent 0.5 with the comment Set_Current. — What gets sent: that model’s real SCPI, with the action name kept as the comment.

Each supported model has a catalog of named operations, each carrying the real command for that model. “Measure DC voltage” on a Keithley DMM6500 and on a Keysight 34465A are the same named action with different commands behind them.

This is the mechanism that keeps TestFlow honest about instrument control. The agent picks action names, the catalog supplies the syntax, and an action name that is not in your instruments' catalogs is rejected before it reaches your workflow.

Instruments with no command catalog

Fully supported, by a different route.

Some hardware has no SCPI catalog at all: a modular switching chassis, a vehicle-bus card, a PXI module driven by a vendor library. TestFlow calls these special instruments, and they are not second-class.

You configure it like any instrument, including its modules or slots.
The agent adds it to workflows with descriptive action names such as Connect Channel with a slot and a channel.
The codegen agent writes an actual driver module implementing those actions, which ships in Script/instruments/ in your package.
The driver is validated before it is accepted, and shown to you for approval before it first touches hardware.
