722 Operating Manual 1403.7458.32 ─ 14
Parameters:
<Impedance> HIGH | G50
HIGH
> 100 k0hm to ground
G50
50 0hm to ground
(requires the extended synthesis assembly (SynEx))
*RST:
HIGH
Example: INP:MOD:IMP HIGH
sets > 100 kOhm to ground.
Manual operation: See "External Input Impedance" on page 244
[:SOURce]:INPut:TRIGger:BBANd:SLOPe <Slope>
Sets the active slope of an externally applied trigger signal at the TRIGGER connec-
tors. The setting is effective for both connectors at the same time.
Parameters:
<Slope> NEGative | POSitive
*RST:
POSitive
Example: INP:TRIG:BBAN:SLOP NEG
activates the falling slope of the external trigger signal at the
TRIGGER connectors.
Manual operation: See "Baseband Trigger Input Slope" on page 143
[:SOURce]:INPut:TRIGger:IMPedance <Impedance>
The command sets the impedance of the trigger and control signal inputs and affects:
●
TRIGGER inputs
●
CLOCK inputs
●
CW, BURST, and LEV_ATT inputs (AUX I/O connector)
Parameters:
<Impedance> G50 | G1K
G1K
1 kOhm to ground
G50
50 Ohm to ground
*RST:
G1K
Example: INP:TRIG:IMP G50
all trigger and control signal inputs are set to 50 ohm to ground.
This setting is recommended in the case of high clock rates.
Manual operation: See "Impedance Trigger/Control Input" on page 142
