4 - 64 COMMAND REFERENCE
INPut<n>:IMPedance
Syntax:
INPut<n>:IMPedance <NRf> | MINimum | MAXimum
<n> [1] | 2 | 3 | 4
<NRf> 50 | 1E6
<MINimum> Equals 5.00E+01 (50
Ω)
<MAXimum> Equals 1.00E+06 (1 M
Ω)
Note: Channel 3 is not applicable for PM33x0B.
Query form:
INPut<n>:IMPedance? [MINimum] | [MAXimum]
<n> [1] | 2 | 3 | 4
Response:
5.00E+01 | 1.00E+06
If <MINimum> was specified, 5.00E+01 (50
Ω) is returned.
If <MAXimum> was specified, 1.00E+06 (1 M
Ω) is returned.
Description:
The input impedance of channel <n> is set according to the impedance parameter
specified. The impedance can be specified low (50Ω) or high (1 MΩ).
After a
*
RST command, the impedance is 1 MΩ.
Restrictions:
The impedance of the following input channels is fixed at 1 M
Ω:
- All channels of the PM3384B CombiScopes instruments.
- Channel 4 of the PM33x0B CombiScope instruments.
Example:
Send
→ INPut2:IMPedance 50 Selects 50Ω input impedance for channel 2.
Front panel compliance:
The INPut<n>:IMPedance command is the remote equivalent of the front panel
50Ω option in the VERT MENU menu.
