4 53210A Input Signal Conditioning
Input Protection
The maximum input voltage (including any DC offset) allowed with 50
impedance is ± 5.125 Vp. If the input voltage exceeds
protection relay opens - changing the input impedance to 1 M
Impedance softkey will still indicate a 50
With the relay open, the corresponding channel key flashes until the input voltage
is removed or red uced below the damage threshold and the key is pressed. This
sets the impedance back to 50
To programmatically determine if the protection relay has been opened, the
command:
INPut[1]:PROTection?
queries the relay state (0 = relay closed, 1 = relay open). With the input voltage
removed or red uced below the damage threshold, the protection relay is reset
(closed) with the command:
INPut[1]:PROTection:CLEar
setting the input impedance back to 50
