5.2.3 Output power of the universal generator
The output amplifier, attenuator and all internal resistors are short-circuit-proof. The
peak value of the current is limited to approx. 250
mA. For a maximum RMS value of
14 V (balanced mode) and 7 V (unbalanced mode), the maximum power dissipation in
the load resistor (with a short circuit in the internal resistor) is 2.5 W or 1.25 W.
5.2.4 Interface Assignment of the Analog Multichannel Generator
With the R&S UPP
‑
B8 option, a multichannel audio generator is available whose 8 out-
puts have been brought out to the pins of a 25
‑
pin D
‑
Sub socket.
As an accessory for the R&S UPP
‑
B8 option (multichannel audio generator), a break-
out cable with a 25
‑
pin D
‑
Sub connector on the one end and eight XLR connectors on
the other end is available (R&S UP
‑
Z8A option; refer to data sheet for the order num-
ber).
The pin assignment corresponds to the TASCAM DB-25 Pinout Standard.
The designation is the channels is Ch3 to Ch10 in agreement with the free channel
selection
5.2.5 Outputs of the Analog Multichannel Generator
The outputs of the analog multichannel generator are unbalanced and have a fixed
output impedance of approx. 25
Ω
. The schematic circuit diagram for the generator
output is shown below.
