SCALE LOG LIN

saves the current limit-line tables in the current mass-storage device ( analyzer memory or memory card). To

verify the current mass-storage device, press SAVE LIMIT . If MAX REG # appears on the analyzer display, the current mass-storage device is analyzer memory. If PREFIX= is displayed, the memory card is the mass-storage device. Press (SAVE_) or CRECALLI), then INTERNAL CARD to change

the current mass-storage device. Press SAVE LIMIT, enter a register number, then press (ENTER) to save the current limit-line table in analyzer memory or on the memory card. When saved on the memory card, limit-line tables are stored with “1-“, the prefix, and the register number entered. When saved in analyzer memory, the register number is saved in a trace register. Trace-register values are restricted to a range between 0 and the number x indicated by MAX REG # = x.

scales the vertical graticule divisions in logarithmic units when LOG is underlined. When the SCALE LOG LIN function is the active function, the logarithmic units per division can be changed. Values may range from 0.1 to

20 dB per division. When LIN is underlined, the vertical scale is in linear mode which has a range of 1 kW to 1 pW. The reference-level value is set to the top of the screen and the bottom graticule becomes zero volts. (Each division of the graticule is one-eighth of the reference level in volts.)

Pressing SCALE LOG LIN always sets the units specified for the current amplitude scale. Pressing (-1 or powering on the analyzer sets the default units.
