TRIGGER:CLKRE
C:CRC:AUTOSCONFIGDEV?
might return
:TRIGGER:CLKREC:CRC:AUTOSC ONFIGDEV 1, indicating that
Auto-saveisenabled.
NOTE. 1 is returned if an Clock Recovery instrument is not present.

Syntax
TRIGger:CLKRec:CRC:CAPabil ities?
Returns
Returns an integer representation of a bit mask t hat indicating the capabilities of
the clock recovery instrument. The bit mask definitions are as follows:
Bit 0 represents HS (High Sensitivity- no loop through data) capability.
Bit 1 indicates DDS capability.
Bit 2 indicates Input analysis capability.
Bit 3 indicates loop calibration refinement capability.
Bit 4 indicates trigger option capability.
Bit 5 indicates jitter spectrum analysis capability.
Bit 6 indicates USB diagnostics capability.
Bit 7 indicates golden PLL mode capability.
Bit 8 indicates optical receiver (DCRJ) capability.
Bit 9 indicates PCIe PLL tester option capability.
Bit 10 indicates jitter scope capability.
Bit 11 indicates DDR capability, allows data input above 14.3 GHz.
Bits are in LSB to MSB order. For example, HS is bit zero (00000000001), DDS
is bit one (00000000010), and so on.
Examples
TRIGGER:CLKREC:CRC:CAPABIL ITIES? might return 40, indicating that both
jitter spectrum a nalysis and loop calibration refinement are present in the clock
recovery instrument.
