Procedure for setting DC bias
Step 1. Press the [Display Format] key.
Step 2. Press the MEAS DISPLAY softkey.
Step 3. Use the cursor keys to select the BIAS field.
Step 4. Use the softkeys or numeric entry keys to enter the test signal level. When
data is entered with the numeric entry keys, the softkey labels are changed to
the appropriate unit labels (mV, V, uA, mA, A).
Idc (A) Vosc(Vrms) Vosc  2  1.15 + Idc  100.2 < 42 V
Idc (A) Iosc (Arms) Iosc  2  115 + Idc  100.2 < 42 V

INCR ++ Increases the oscillator’s output level with a resolution shown in
Table 3-20 or Table 3-21.
INCR + Increases the oscillator’s output level with a resolution shown in
Table 3-16 to Table 3-18.
DECR - Decreases the oscillator’s output level with a resolution shown in
Table 3-16 to Table 3-18.
DECR -- Decreases the oscillator’s output level with a resolution shown in
Table 3-20 or Table 3-21.
