You can send most headers and data in short form, marked with bold letters.
Example
: FREQ
UENCY
is in short form
FREQ
SC1L
EVEL
is in short form
SC1L
All headers can be sent as command headers to program the generator and also as query
by adding a question mark. The instrument returns its actual setting in response to the
query.
Example
: FREQ 471250E3
Sets the instrument to
471.25 MHz
FREQ?
Response
: FREQ 471.25E6

K
HZ |
M
HZ |
G
HZ]
Remark:
NRf
is the frequency range from 32.00 MHz to 900.00 MHz in 50 kHz
steps. If no suffix is sent, the instrument sets HZ (Hertz).
Example:
FREQUENCY 203.25 MHZ
or
FREQ 203.25E6
sets the vision carrier frequency to 203.25 MHz.

]
Remark:
NRf
is the level range from 0.01 mV to 100 mV in
0.01 mV steps to 10 mV and in 0.1 mV steps to 100 mV
(20 to 100 dVµV in 1 dB steps).
If no suffix is sent, the instrument sets V (Volts).
Example:
LEVEL 1MV
or
LEVE 0.001
sets the vision carrier level to 1 mV.
