leads to the series of menus used to perform a high-accuracy two-port calibration without an S-parameter test set.

This calibration procedure effectively removes directivity, source match, load match, isolation, reflection tracking, and transmission tracking errors in one direction only. Isolation correction can be omitted for measurements of devices with limited dynamic range. (The device under test must be manuaIly reversed between sweeps to accomplish measurement of both input and output responses.) The required standards are a short, an open, a thru, and an impedance-matched load.

This mode does not measure each sweep, but corrects each point with the data currently in the power meter correction table.

provides a tabular listing on the analyzer display of the key parameters for both channels. The screen menu is presented to allow hard copy listings and access new pages of the table. Four pages of information are supplied. These pages list operating parameters, marker parameters, and system parameters that relate to control of peripheral devices rather than selection of measurement parameters.

defines the standard type as an open, used for calibrating reflection measurements. Opens are assigned a terminal impedance of infinite ohms, but delay and loss offsets may still be added. Pressing this key also brings up a menu for defining the open, including its capacitance.

gets data from an HP-IB device set to the address at which the analyzer expects to lind a power meter. The data is stored in a title string. The analyzer must be in system controller or pass control mode.

while creating a sequence, this softkey will insert a command that selects the single bit (0 to 4) that a sequence will be looking for from the GPIO bus.

while creating a sequence, this softkey inserts a command to jump to another sequence if the single input selected is in a high state.

while creating a sequence, this softkey inserts a command to jump to another sequence if the single input selected is in a low state.

sets the printer or plotter port to parallel.

toggles the parallel output port between the copy and GPIO output modes.

allows you to input a number (0 to 255) in base 10, and outputs it to the bus as binary, when the parallel port is in GPIO mode.

pauses the sequence so the operator can perform a needed task, such as changing the DUT, changing the calibration standard, or

other similar task. Press ~~~~~.~~~~~~~ when ready.
