The TTAA? query will return the amplitude in the currently displayed units. For
example, if the display shows 10.0 V
the units indicator is sent along with the command (such as TTAA?VP), the
returned units will match the units indicator and the amplitude will be returned in
those units.
The TTBA command sets the Tone 2 amplitude to x. The value x must consist of
the numerical value and a units indicator. The units may be VP (V
DM (dBm) or DV (dBV). For example, the command TTBA1.0VP will set the
Tone 2 to 1.0Vpp. The maximum value for the sum of Tone 1 and Tone 2
amplitude, as well as the ratio of the two, is limited as described in chapter 3. If
the DS360 must modify the amplitude of either Tone 1 or 2, due to under or over
ranging, a message is sent on the front panel and bit 3 in the DDS register is set.
The TTBA? query will return the amplitude in the currently displayed units. For
example, if the display shows 10.0 V
the units indicator is sent along with the command (such as TTBA?VP), the
returned units will match the units indicator and the amplitude will be returned in
those units.
The TTAF command sets the Tone1 frequency to x Hertz. The TTAF? query
returns the current Tone1 frequency. The frequency is set and returned with
10mHz resolution.
The TTBF command sets the Tone 2 frequency to x Hertz. The TTBF? query
returns the current Tone 2 frequency. The Tone 2 frequency must be a legal value
for the 2-Tone type selected (see TTMD). If Tone 2 is a sinewave, the frequency
is set and returned with 10mHz resolution. If Tone 2 is a squarewave, the
frequency is set and returned with 2 digits of resolution (ie. 4.8kHz or 110Hz, but
not 101Hz).
The TTMD command sets the Tone 2 mode to either sine (i=0) or square
(i=1).The TTMD? query returns the current Tone 2 mode.
