4.12.1.1 Frequency
The frequency command controls the frequency of the pulse in the continuous trigger mode. It
is the inverse of the period.
COMMAND TYPE: Setting or Query
SETTING
Syntax: [:SOURce]:FREQuency[:CW|FIXed]<ws><frequency>[units]
Arguments:
Type: NRf
Units: MHz, kHz, Hz (default)
Range: 0.1Hz to 50MHz
Rounding: To the resolution of the range.
Examples: :FREQ 5KHZ
:FREQ 5E3
QUERY
Syntax: [:SOURce]:FREQuency[:CW|:FIXed]?
Examples: :FREQ?
Response: NR3
CONSIDERATIONS: FIXed is an alias for CW.
4.12.1.2 High Voltage Level
This command is used to set the high level of the pulse.
COMMAND TYPE: Setting or Query
SETTING
Syntax: [:SOURce]:VOLTage[:LEVel][:IMMediate]:HIGH<ws><high level>[units]
Arguments:
Type: NRf
Units: MV, V (default)
Range: -9.5V to +10V
Rounding: To 10mV
Examples: VOLT:HIGH 4V
QUERY
Syntax: [:SOURce]:VOLTage[:LEVel][:IMMediate]:HIGH?
Examples: :VOLT:HIGH?
Response: NRf
CONSIDERATIONS:
1) The high level must be greater than the low level.
2) The difference between the levels must conform to 0.5V ≤ difference ≤ 10V
3) The high level may not exceed the high limit.
4.12.1.3 Low Voltage Level
