Signal Generator Memory
Signal Generator Memory
The signal generator provides two types of memory, volatile and non-volatile.
NOTE User BIT, and User PRAM references are only applicable to the E4438C with Options 001,
002, 601, or 602, and E8267D with Options 601 or 602.
User FIR references are only applicable to the N5182A with Options 651, 652, or 654,
E4438C with Options 001, 002, 601, or 602, and E8267D with Options 601 or 602.
Volatile Random access memory that does not survive cycling of the signal generator
power. This memory is commonly referred to as waveform memory (WFM1) or
pattern RAM (PRAM). Refer to Table 7 for the file types that share this memory:
Non-volatile Storage memory where files survive cycling of the signal generator power. Files
remain until overwritten or deleted. Refer to Table 7-1 on page 282 for the file
types that share this memory:
