AH 1:
— acceptor handshake
SH 1:
source handshake
L4:

T6:
talker function
RL 1:

SR 1:
service request SRO
LL
amplitude (dBm)
(= key dBm)
V
for amplitude
dBm for leve!
Examples:
F 1900
F3.125
F2E6
frequency input 1 kHz
frequency input 3.125 Hz
frequency input 2 MHz
If the parameter is input in the exponential form, then please note that only the first digit of the ex-
ponent is considered; further digits are accepted but ignored.
The frequency value F 4E23, for example, is identified as F4E2 = 409 Hz. The size of the mantissa in
exponential values, of integers and reals are restricted to the largest possible number of digits on the
corresponding display panel, i. e. 8 digits for frequency inputs, 3 digits for the input of levels etc.. More
digits can be entered than are actually possible, but only the first digits of the input string will be
recognised.

Numeric extensions for modulation
MA (x) amplitude modulation
X
=
@ switches off the operation
MO
"modulation off"
1 internal modulation
(= key INT)
2 external modulation (= key EXT)
The numeric extension must be sent in addition to the command 'MA' in order to transmit the required
additional information; the figure @ switches off the respective function.
