AUX In Trigger: Turn on this control for stand-alone operation. When turned on, positive voltage (logic
high) across the AUX port input will trigger a test. This enables the SLM-8 to function without an IQ System after
it has been configured. With the LED indicators on the front panel it is easy to see the pass/fail status of any
channel.
AUX Out P/F Report: Turn on this control if you want to use the AUX port output to signal whenever one
or more channels fails an impedance or frequency test. The SLM-8 uses reverse logic for this feature. It turns
on the AUX output when all channels have passed all tests and it turns off the AUX output when one or more
channels fails a test. In this way the AUX output can also signal a power loss.
Channel Configuration
The following parameters configure the individual settings of each channel.
Label: Sets a text string that identifies the channel. A label can be up to 20 characters in length and is stored
in the memory of the SLM-8 where it is backed up in case of power failure.
Acquire Mode: Determines which test(s) will be performed on the channel. The possible settings are:
Off-Pass: Do not test but report a “passed” status.
Off-Report: Do not test but continue to report the previous test results.
Impedance: Test the impedance response only.
Frequency: Test the frequency magnitude response only.
Imp/Freq: Test both the impedance and frequency magnitude response.
Reference: Measure the reference impedance response and reference frequency magnitude re-
sponse.
Start (Hz): Sets both the beginning frequency of a test and the beginning frequency of the returning data.
Stop (Hz): Sets both the ending frequency of a test and the ending frequency of the returning data.
View Curve: Serves as both a parameter and a control. As a parameter it sets the contents the Curve
screen (by pressing the “Space Bar”). As a control is changes the display to the Curve screen (by pressing
E). The possible settings are:
Impedance: Display only the impedance response from the most recent test on the Curve screen.
Frequency: Display only the frequency magnitude response from the most recent test on the Curve
screen.
Imped Ref: Display only the reference impedance response on the Curve screen.
Freq Ref: Display only the reference frequency magnitude response on the Curve screen.
Imped w/Ref: Display both the impedance response from the most recent test and the reference
impedance response on the Curve screen.
Freq w/Ref: Display both the frequency magnitude response from the most recent test and the reference
frequency magnitude response on the Curve screen.
