Waveform Memory Format
This section describes the formats of the commands which enter data into
the wave memory of a TEGAM, Inc. arbitrary waveform generator via the GPIB
or RS-232 interface.

The contents of the waveform memory for wave X (X = 0..99) are changed by a
single command formatted according to the IEEE 488.2-1987 standard, and has
the following syntax:
<command header> <start address>,<data>[,<data> ... ];
As a command for the GPIB or RS-232, a <command header>, followed by the
address of the first memory cell to be set, followed by one or more <data> items
and terminated by a semicolon. The <start address> and <data> items are
separated by commas, with a space or tab separating the <command header>
from the <start address> item. The numbers specified by the <data> items are
stored in successive addresses of the wave memory.
The <command header> is a string, whose value depends only on the wave to be
set:
Wave Command Header Value
0 WVFM:WAVE 0;MEM
1 WVFM:WAVE 1;MEM
99 WVFM:WAVE 99;MEM
The <start address> is a decimal number between 0 and 65471. It sets the
starting address where the <data> will be downloaded in waveform memory.
The <data> items are decimal numbers between -32768 and 32767. If the
AMPL (Amplitude) parameter is set to 10V, the following data: -32768, 0,
32767 would produce -10 Volts, 0 Volts, and 10 Volts, respectively, on the
output.
Examples:
An 8 point positive Ramp down loaded into wave 1, address 0.
WVFM:WAVE 1;MEM 0,0,4681,9362,14043,18724,23405,28086,32767
An 8 point sine wave down loaded into wave 2, address 48.
WVFM:WAVE 2;MEM 48,0,23169,32767,23169,0,-23170,-32768,-23170
