For example: FF FF D1 64 = –11932 As it is based on 1024 per dB, divide
by 1024 to get the dB value (–11.652).

OGD

Output Graph Data

DATA OUTPUT

Syntax:

OGD

Remarks:

Outputs the next complete set of graph data.
The format is as follows:
OGD ,,,ment_n>...<\n>
The first number in the string is the number of elements to follow, and is al-
ways 200 for the ML2430A Series.

OGSD

Output Valid Samples Array (power vs. time mode only)

DATA OUTPUT

Syntax:

OGSD

Remarks:

A power verses time chart plots the readings on a scrolling chart from left
to right. If GRCP (connect points) is on and no new data has been re-
ceived for a time slot, the graph is plotted with the same value as the previ-
ous time slot but the data for that sample position is not marked as valid.
This command will read out an array of 1's and 0's that indicate whether
the data for that time slot is valid. For example, '1' for valid and '0' for con-
necting data only.

Because the time between reading the data and reading the valid sample
data may shift the valid samples out of sync with the graph read, it is rec-
ommended that a 'HOLD ON' be issued before reading the graph and
sample data, and a 'HOLD OFF' after. This will make sure that the sample
data and the graph data agree.

If not in Power vs. Time mode, this command will set an execution error.
