Front Panel Summary
Signal Inputs Single Ended (A), True Differential (A-B), or Current (I)
Signal Filters Bandpass: Q-of-5 Auto-tracking filter (In or Out)
Line Notch: Q-of-10 Notch Filter at line frequency (In or Out)
2XLine Notch: Q-of-10 Notch Filter at twice line frequency (In or Out)
Sensitivity Full scale sensitivity from 100 nV to 500 mV RMS for voltage inputs
or from 100 fA to 500 nA RMS for current inputs.
Dynamic Reserve Select Dynamic Reserve Stability Sensitivity Ranges
LOW 20 dB 5 ppm 1
µ
V to 500 mV
NORM 40 dB 50 ppm 100 nV to 50 mV
HIGH 60 dB 500 ppm 100 nV to 5 mV
Status Indicators OVLD Signal Overload
UNLK
PLL is not locked to the reference input
ERR Illegal or Unrecognized command
ACT RS232 or GPIB interface Activity
REM Remote mode: front panel has been locked-out
Display Select X Signal Amplitude at the selected phase (AcosØ)
OFST Display the offset which is being added to the signal output
NOISE Compute and display the noise on the signal
Analog Meters Displays Signal, Offset, or Noise as a fraction of full scale
Output LCD's Displays Signal, Offset, or Noise in absolute units
Output BNC's Output follows Analog Meter, ± 10 V for ± full scale
Expand Multiplies the Analog Meter and Output voltage by a factor X1 or X10.
REL Set the Offset to null the output: subsequent readings are relative readings.
Offset Enables or Disables Offset, and allows any offset (up to full scale) to be entered.
Time Constants Pre-filter has time constants from 1 mS to 100 S (6 dB/Octave)
Post-filter has time constants of 0, 0.1 or 1.0 S (6 dB/Octave)
ENBW Equivalent Noise Bandwidth. Specifies the bandwidth when making Noise
measurements. (1Hz or 10 Hz ENBW)
Reference Input 1 M
Ω
Input, 0.5 Hz to 100 KHz, 100 mV minimum
Reference Trigger Trigger on rising edge, zero crossing, or falling edge
f/2f Mode PLL can lock to either X1 or X2 of the reference input frequency
Phase Controls Adjust phase in smoothly accelerating 0.025° steps, or by
90° steps. Press both 90° buttons to zero the phase.
Reference LCD Display reference phase setting or reference frequency
Power Switch Instrument settings from the last use are recalled on power-up
