PSTF(?) [ j ] { , f { HZ | KHZ | MHZ } }
The PSTF j, f
whenever the internal frequency keypad is displayed. The parameter j (0–3) selects a
preset F1–F4. The value of f will be rounded to 6 digits or 0.1 mHz, whichever is greater.
The value of f is limited to 1 mHz ≤ f ≤ 4 MHz.
Example
PSTF 1, 12.34 KHZ
PSTF 1, 12340
PSTF? 1
PSTA(?) [ j ] { , v { NV | UV | MV | V } }
The PSTA j, v
available whenever the sine out amplitude keypad is displayed. The parameter j (0–3)
selects a preset A1–A4. The value of v will be rounded to 3 digits or 1 nV, whichever is
greater. The value of v is limited to 1 nV ≤ v ≤ 2.0 V.
Example
PSTA 2, 12.3 MV
PSTA 2, 0.0123
PSTA? 2
PSTL(?) [ j ] { , v { NV | UV | MV | V } }
The PSTL j, v
available whenever the sine out dc level keypad is displayed. The parameter j (0–3)
selects a preset L1–L4. The value of v will be rounded to 3 digits or 0.1 mV, whichever is
greater. The levels may be programmed from −5.00 V to +5.00 V.
Example
PSTL 0, 1.23 V
PSTL 0, 1230 MV
PSTL? 0
