These lines distinguish between an external controller and the
Instrument BASIC and set the GPIB address.
These lines substitute the settings of adapter selection, measurement
parameters, and limits of dc bias output and of dc bias range to the
variables Adapter$, Meas_para$, Dc_b_max, Dc_b_rng$,
respectively.
These lines substitute the parameter settings necessary for making a
list sweep table to the variables List_star(*), List_stop(*), Nop(*),
Osc_mode$(*), Osc_pow(*), Dc_b_mode$(*), Dc_bias(*),
Bw_fact$(*), and P_ave(*).
These line substitute the display-related parameter settings to the
variables Split$, Accumulate$, Disp_a$, Disp_b$, Fmt_a$, Fmt_b$,
Top_v_a, Btm_v_a, Ref_p_b, Ref_v_b, Scal_b, Phase_unit$, and
Exp_phase$.
These lines reset the Agilent 4294A and then set the adapter selection
to the variable Adapter$.
These lines make a list sweep table.
These lines set the measurement parameter to Meas_para$, limit of dc
bias output to Dc_b_max, dc bias range to Dc_b_rng$, On/Off setting
of dc bias to On and set the type of sweep to List Sweep and the
display format to Segment By Segment.
These lines set the display parameters common to traces A and B.
indicate the message of completion, and end the program.
