General
Display: Segmented 24-character alphanumeric LCD (backlighted)
Built-in Features: Self-check, diagnostics, display and keyboard lockout, overload indicator, HP-IB teach-learn mode
Data Output Over HP-IB bus; varies with frequency and resolution
Auto Mode: >100 readings/s, 10 kHz resolution, no math functions, "DUMP" mode
Manual mode: >120 readings/s, 10 kHz resolution, no math functions, "DUMP" mode
Math Functions: Scale, offset, smooth (exponential averaging)
Sample Rate: Variable from less than 50 ms between measurements to HOLD, which holds the display indefinitely or
until trigger occurs.
Display Rate: 5/s, variable over HP-IB
Sleep Mode: Input 1 emissions reduced to <-70 dBm typical when sleep mode or Input 2 is selected.
