Signal Inputs | Single Ended (A), True Differential | ||||
Signal Filters | Bandpass: | ||||
| Line Notch: | ||||
| 2XLine Notch: | ||||
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 | |

| 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 | |||
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 | |||||

ENBW | Equivalent Noise Bandwidth. Specifies the bandwidth when making Noise | ||||
| measurements. (1Hz or 10 Hz ENBW) |
| |||
Reference Input | 1 MΩ 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 | ||||
