Stationary installation (THM1176-MF and -HF only):
Removing the cap also reveals a mounting point that allows the probe to be
permanently mounted or attached to a scanning arm. The exact position of
the field-sensitive point can be determined by optical sighting.
3-6 HOST COMPUTER INTERFACE
•
USB interface:
Compliance with the USB 2.0 mechanical, electrical and protocol standard
provides basic connectivity with any USB-capable computer. The
instrument supports USB full-speed communication (12 Mbps).
•
Standardized USB class driver:
Compliance with the USB Test & Measurement Class (USBTMC) allows
the instrument to be connected without installing a custom USB driver. All
that is required is a generic class driver for test and measurement
equipment, as provided by suppliers of instrumentation software.
•
Standardized IEEE488.2 protocol:
Compliance with the USB488 protocol specification for USBTMC provides
all the capabilities of an IEEE488 instrument on the USB bus. IEEE488,
derived from HPIB/GPIB, is the world’s most widely used instrumentation
protocol. IEEE488 compliance allows any VISA library (Virtual Instrument
Software Architecture) to control every aspect of the instrument.
•
Standardized instrument command protocol:
The SCPI standard (Standard Commands for Programmable Instruments)
is the standard developed and used by large instrumentation
manufacturers such as Tektronix and HP/Agilent/Keysight, and provides a
programming interface familiar to many instrumentation system
programmers.
