ZTEC function: SCP2:
Example: Perform scope self-test:
Status
KXCI command: :SCOPE:STATUS? registerSelect
Purpose: Returns the current state of all status event or condition registers.
Parameters: registerSelect = 0: Condition Register
Returned values: statusRegister - Returns the present condition of the status register:
4200-901-01 Rev. S / May 2017
Returns a decimal value. The binary equivalent of the decimal value indicates which bits of the Status
Test Register are set (1) or clear (0). For example, if decimal value 6 is returned, the binary equivalent is
0000000000000110. This binary value indicates that Bits 1 and 2 are set. The SRAM Test and ROM Test
has failed.
Test Status Register:
Bit 0 - Baseboard Test Failed Bit
Bit 1 - SRAM Test Failed Bit
Bit 2 - ROM Test Failed Bit
Bit 3 - Unused
Bit 4 - Reference Oscillator Test Failed Bit
Bit 5 - DRAM Test Failed Bit
Bit 6 - Flash Memory Test Failed Bit
Bit 7 - Unused Bit
Bit 8 - Input 1-2 Register Test Failed Bit
Bit 9 - Input 1 RAM Test Failed Bit
Bit 10 - Input 2 RAM Test Failed Bit
Bit 11 - PLL Test Failed Bit
Bit 12-15 - Unused

:SCOPE:SELFTEST
Return to
= 1: Event Register
Selects whether to download the status condition or event registers. Condition registers indicate the
current state of the instrument. Event registers indicate states that occurred since the last event check.
Returns a decimal value. The binary equivalent of the decimal value indicates which bits of the Status
Test Register are set (1) or clear (0). For example, if decimal value 20 is returned, the binary equivalent is
0000000000010100. This binary value indicates that Bits 2 and 4 are set.
Status Register:
Bit 0 - Unused Bit
Bit 1 - Unused Bit
Bit 2 - Error Log Not Empty Bit
Bit 3 - Questionable Summary Bit
Bit 4 - Message Available Bit
Bit 5 - Standard Event Summary Bit
Bit 6 - Master Summary Bit
Bit 7 - Operation Summary Bit
frequencyRegister - Returns the present condition of the frequency register:
Returns a 0 if the PLL is locked or a 1 if the PLL is unclocked.
Frequency Register:
Bit 0 - PLL Unlocked Bit
Bits 1-7 - Unused Bits
