AM700 Audio Measurement Set User Manual
The digital generator is also very flexible. It can produce test signals in AES/EBU,
SPDIF, Optical, and raw data forms at a variety of sample rates. Like the analog
generator, it can produce independent signals on either channel. In addition to the
audio test signals, you can use this generator to manipulate the Channel Status Data
and User Data bits in the serial data stream. Varying types and degrees of corruption
can be added to the output to permit testing of devices under real-world conditions.
When the Audio Analyzer application is in use, the internal generator sweeps can be
driven in a closed-loop mode of operation. This mode is very useful for stimulating
a device under test and waiting for the Analyzer to acquire the signal output from
the device under test before stepping to the next step in the sweep. Propogation
delays through the device under test and the settling time needed to produce a stable
signal are accounted for by the Settling Detection feature so that, if possible, settled
data is acquired at each step before advancing to the next step.
Installation of the AM700
This information includes the power requirements, power cord information, and fuse
information for installing the AM700. Calibrating the touch screen and setting the
real time clock are also included here as part of the initial start-up routine after
installation.
The AM700 operates with line frequencies of 50 Hz or 60 Hz over two line voltage
ranges. The nominal setting of the low voltage range is 115 VAC. The nominal
setting of the high voltage range is 230 VAC. The AM700 power requirement is
185 watts or 230 volt-amperes at maximum power consumption.
There are two power switches on the AM700. They are the main power switch, a
push button switch on the rear panel above the power cord receptacle (see
Figure 1-1), and the Stby/On button on the front panel. Both must be on to operate
the instrument.
WARNING. Dangerous voltages are present within the Power Supply module when
the rear-panel power switch is on, regardless of the position of the front-panel power
switch. Do not operate the AM700 with any covers removed. Refer all servicing of
the instrument to a qualified service person.
