Programming the Status Register System 4
Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 123
Data Questionable Frequency Transition Filters (negative and positive)
Specifies which types of bit state changes in the condition register set corresponding bits in
the event register. Changes can be positive (0 to 1) or negative (1 to 0).
Data Questionable Frequency Event Register
Latches transition events from the condition register as specified by the transition filters.
Event registers are destructive read-only. Reading data from an event register clears the
content of that register.
Data Questionable Frequency Event Enable Register
Lets you choose which bits in the Data Questionable Frequency Event Register set the
summary bit (bit 5 of the Data Questionable Condition Register) to 1.
7−14 Unused. These bits are always set to 0.
15 Always 0.
Query: STATus:QUEStionable:FREQuency:CONDition?
Response: The decimal sum of the bits set to 1.
Bit Description
Commands: STATus:QUEStionable:FREQuency:NTRansition <value> (negative
transition) or STATus:QUEStionable:FREQuency:PTRansition <value>
(positive transition) where <value> is the sum of the decimal values of the bits you
want to enable.
Queries: STATus:QUEStionable:FREQuency:NTRansition?
STATus:QUEStionable:FREQuency:PTRansition?
Query: STATus:QUEStionable:FREQuency[:EVENt]?
Command: STATus:QUEStionable:FREQuency:ENABle <value>, where <value> is the
sum of the decimal values of the bits you want to enable.
Example: Enable bit 4 and bit 3 so that whenever either of those bits are set to 1, the Data
Questionable Frequency summary bit of the Data Questionable Condition Register is set
to 1. Send the command STAT:QUES:FREQ:ENAB 520 (16 + 8).
