Figure 4.7 – The monitor cable for the Series 8 and the Series 7 PGSTAT
The following signals are available:
EOUT – This output corresponds to the differential potential of RE versus S 57. The
output voltage will vary between ±10 V. The output impedance is 50 Ω, so a
correction should be made if a load < 100 kΩ is connected. The minimum load
impedance is 200 Ω.
iOUT – This signal corresponds to the output of the current-to-voltage converter
circuit of the PGSTAT. A 1 V signal corresponds to {1 x the selected current range}.
The output level varies between ± 10 V. The output impedance is 50 Ω, so a
correction should be made if a load < 100 kΩ is connected. The minimum load
impedance is 200 Ω.
EIN – This is an analog voltage input, that can only be used after it has been
enabled in software, using the Autolab control command (see Figure 4.8). Do not
leave it enabled unnecessarily, to prevent noise pickup by the system. This input is
directly connected to the summation point, Σ, of the PGSTAT. In PSTAT mode, a 1

The Eout value corresponds to -WE(1).Potential.
