Menu Description
Connector
Press the Connector softkey to select the output connector type.
–Bal
Balanced mode outputs a pair of differential signals which are equal in amplitude but 180 degrees out of phase on the
XLR positive and negative pins.
–UnBal
Unbalanced mode outputs a signal referenced to ground on the BNC output connector.
–Com
Common mode outputs a pair of equal amplitude and in-phase signals on the XLR positive and negative pins. The
common mode test signal is applied to both pins 2 and 3 or the XLR connector, while pin 1 is connected to the
return signal.
– IEC60268
The common mode test signal is applied to both pins 2 and 3 or the XLR connector, while pin 1 is connected to the
return signal. An additional 10 Ω output series resistance is added to pin 2 or 3.
Impedance
Press the Impedance softkey to select the output impedance value.
For Bal, Com, and IEC60268
– 600 Ω
– 100 Ω
–40 Ω
For UnBal
– 600 Ω
–50 Ω
–20 Ω
