Graticle:  Internally generated.  Single and dual grid mode

Expansion:  Dual zoom horizontal expansion operates simultaneously on live, stored and processed waveforms, expanding up to 100 times.   Vertical expansion from 0.4 up to 2 times for non-processed waveforms, up to 10 times for processed waveforms.

Screen Dump:  Single or multi-pen digital plotters are menu selected.  Supports the HP 7400 series and compatible models.

Cursors:  Two time cursors.  Two voltage cursors.   A cross-hair marker measures absolute voltage versus signal ground as well as the time relative to the tripper.  Time and cross-hair cursors indicate Hz and dB or volt values when and FFT spectrum analysis is made.

Remote Control

RS-232-C Ports:  Two:  for computer/terminal control and plotter connection.  Asynchronous up to 19200 baud.

GPIB Port (optional):  IEEE - 488

Waveform Processing WP01 and WP02:

Routines are called and set up via menus. Extensive signal processing in both time and frequency domains is provided by optional firmware packages. These include FFT spectrum analysis, arithmetic functions, integration, differentiation, square root, square, averaging (continuous and summation), and smoothing, as well as Extreme monitoring.
