Oscilloscopes
The 54600 series of oscilloscopes offers multiple-channel configurations, including 2- and 4-scope channels; the mixed signal oscilloscope (MSO) has 2+16 channels (two analog plus 16 integrated-digital), 2 Mbytes of MegaZoom deep memory that reportedly respond instantly to control inputs, and a high-definition display system. Among the triggering features are: edge, pulse width, pattern, sequence, TV, and Inter Integrated Circuit bus.

Flow
computer
SUPERtrol II, a multi-function flow computer with built-in modem, data logging, and a two-way paging transceiver, displays and outputs compensated flow calculations for gases, liquids, steam, and heat. Measured parameters include uncompensated volume rate, corrected volume rate, mass rate, temperature, pressure, and density. The instrument is equipped with serial RS-232 communication for connection to the wireless transceiver, printers, modems, or computers.

Digital
oscilloscopes
The newest Waverunner™series of digital oscilloscopes is reported to attain 1 GS/s at 2 Mpoints on each of two channels, or 500 MS/s and a 1 Mpoints/CH on each of four channels, and captures a signal of 2 MS duration at 1 GS/s. The external input channel is available for triggering on an additional signal. Some other features include: SMART Trigger®, averaging and enhanced resolution, FFT analysis, pass/fail testing, and internal floppy drive with a 10 Base-T Ethernet interface option.

Counting
logger
DL400C is a 16-bit, miniature, standalone 8 input pulse-counting logger that has a memory capacity of up to 65,535 counts with a built-in 2-year lithium battery. The unit also has a built-in clock and eight digital inputs, which also can be configured as seven pulse counting inputs with one trigger channel. The digital input signal can be a contact closure or a state change of up to 24V. A typical usage would be as a roadside traffic counter to determine peak traffic patterns.
