D1500 Quick Start

Using the D1500 as an RTA.

This section will take you through a quick set-up us-
ing the D1500 as a real time frequency analyzer.
First, remove all packing materials (save them in case
of need for future service) and decide where the unit
is to be physically placed—it can be used free-stand-
ing or mounted in a standard 19" rack.
Before you move ahead, you should become familiar
with the various control switch sections. The D1500
front panel switches are set up in groups related to
the function or parts of the operating system they
control. Some switches are placed individually, since
they are dedicated to a single function, and other
switches, are arranged in groups since their function-
ality is related. The D1500 function switch sections
are arranged on the front panel as follows:
BY PASS
AUTO EQ
PARAMETERS
NAVAGATION

GLOBAL

MIDI
LOAD and STORE
In this quick start example, we'll take you through
the BYPASS and GLOBAL sections, as well as the NAV-
IGATION and PARAMETER sections. AUTO EQ, MIDI
and the LOAD and STORE switches and functions will
be covered in detail later on in this manual.
You should know this!
Several of the modes that are controlled by the Navi-
gation switches, have a number of parameters as-
sociated that can be adjusted for finer control. Each
of these parameters will be explained in detail later
on in this manual, however you should know that
you can see these parameters by holding the mode
switch for 2 seconds. For example, if you press and
hold the RTA switch for 2 seconds, you will see all the
LED's on the parameter switches light. That indicates
that all these parameters can be adjusted in the RTA
mode. If you press and hold the EQ switch for two
seconds, no parameter switches LED's light, indicat-
ing there are no adjustable parameters.
You should know this too !
Many of the D1500 control buttons are capable of
accessing more than one parameter, so as you press
the switch, you will page through the available pa-
rameters. For example, the GLOBAL switch will toggle
between the parameters Input selection and Mic
Gain. You can edit the parameters of any of these
functions by using the large Data Wheel located by
the main LCD display.
GLOBAL
The GLOBAL control allows you to set up the various
system parameters including selecting the input/
output and control for the measurement micro-
phone input.

Selecting the Input

The D1500 accepts inputs from any of the installed
I/O boards including the optional DIO1 Digital I/O or
AIO2, I/O board with premium analog-to-digital and
digital-to-analog converters. You can load any com-
bination of these I/O boards in each of the Option 1
or Option 2 card slots. You can also select the input
from a connected measurement microphone here.
To access the input follow these steps:
• Press the GLOBAL control switch once or twice
until you see the: Inp ......
• Use the Data Wheel to select OPT 1, OPT 2 or MIC.
NOTE:
Once you make an edit to the Global set-up, the red
GLOBAL LED will flash indicating that a change has been
made to the original set-up. You will also see that the red
.
STORE LED is illuminated
• To keep the new changes, press STORE again to
confirm the change to be saved and you will exit the
