VALID ONLY FOR BILATERAL DEVICES
Information
Message
This message is displayed when an enhanced reflection calibration is initiated.
If the device tested is not a bilateral device, the enhanced reflection calibration
will cause errors in the measurement results.
A bilateral device has similar forward and reverse transmission characteristics.
Examples of bilateral devices are passive devices (filters, attenuators, and
switches). Most active devices (amplifiers) and some passive devices (isolators
and circulators) are not bilateral.
WAIT: ECal MODULE BEING READ
Information
Message
The data from ECal is being read by the network analyzer.
WAITING FOR CLEAN SWEEP
Information
Message
In single sweep mode, the instrument ensures that all changes to the
instrument state, if any, have been implemented before taking the sweep. The
command that you have initiated is being processed and will not be complete
until the new sweep is completed. An asterisk * is displayed in the left margin
until a complete fresh sweep has been taken.
WAITING FOR DISK
Information
Message
This message is displayed between the start and finish of a read or write
operation to a disk.
WAITING FOR GPIB CONTROL
Information
Message
You have instructed the analyzer to use pass control (USEPASC). When you
send the analyzer an instruction that requires active controller mode, the
analyzer requests control of the bus and simultaneously displays this message.
If the message remains, the system controller is not relinquishing the bus.
WRITE ATTEMPTED WITHOUT SELECTING INPUT TYPE
Error Number
32
You have sent the data header “#A” to the analyzer with no preceding input
command (such as INPUDATA). The instrument recognized the header but did
not know what type of data to receive. Refer to the programmer’s guide for
command syntax information.
WRONG DISK FORMAT, INITIALIZE DISK
Error Number
77
You have attempted to store, load, or read file titles, but your disk format does
not conform to the Logical Interchange Format (LIF) or DOS format. You must
initialize the disk before reading or writing to it.
