Source Microphone:

Off

Input X-weighted

Input C-weighted

Input Z-weighted

DC Voltage

Generator

Accelerometer and

Direct:

Off

Input Linear

Output to the Output socket on the connector

panel. Select between Off and the input signal

for monitoring purposes.

The L

setting will output the X-weighted

sound level as a voltage between 0 V and 4 V.

Use the DC Voltage parameter to calibrate the

connected equipment by setting the DC

Output.

Use Generator parameter to output the signal

specified by the Generator settings.

Note 1: If you do not want to output the signal,

then select Off to economise the power.

Note 2: X = frequency weighting A or B. ‘A’

requires that the Broadband (excl. Peak)

parameter is set to AC or AZ. ‘B’ requires that

the Broadband (excl. Peak) parameter is set

to BC or BZ.

Note 3: The Generator setting is only

available for Frequency Analysis templates

DC Output (20 mV/dB) 0.0 to 200.0 dB Source = DC Voltage will output:

0V for DC Output = 0dB and

4V for DC Output = 200 dB

Output Gain Input –60.0 dB to 60.0 dB Output gain of the input signal. Key in a gain

value (0.1 dB resolution) for the input signal.

Use ‘@’ to assign the new value for immediate

response at the output – or use the up/down

navigation keys to increment/decrement the

value in steps of 1 dB.

Note: 0 dB means 1 V output for 1 V input.
