Options
Option 21, 41: Power meter function
Frequency range 100 kHz to 32 GHz, Depends on the power sensor used.
Applicable power sensor
MA4601A (100 kHz to 5.5 GHz), MA4701A (10 MHz to 18 GHz),
MA4703A (50 MHz to 26.5 GHz), MA4705A (50 MHz to 32 GHz)
Power measurement range –20 to +20 dBm
Display
Selectable from W, dBm, and dB (RELATIVE), Digital 4 digit display, 20% over range,
Power range: 4 range/10 dB step (Measurement level range is listed on the power sensor specifications.)
Range switching Auto, manual (settable to arbitrary range irrespective of range hold or input level)
Accuracy
±0.7% (W mode), ±0.03 dB (dBm mode, dB (RELATIVE) mode)
∗
Pressing ZERO ADJ key allows automatic adjustment to zero point.
Zero setting ±0.5% of full scale Typical value (100 µW range of maximum sensitivity)
Zero move between ranges ±0.2% (after zero setting at 100µW range of maximum sensitivity)
Calibration oscillator frequency 50 MHz
Calibration oscillator level 1 mW ± 1.2% (for one year)
Averaging An average count can be set from 2 to 10.
Option 34: 4 GHz LO output
Frequency
Frequency: 4 GHz
Frequency accuracy: ± (4 GHz x reference frequency accuracy) ±1 Hz
Output level –10 dBm Typical
Spurious
≤
–40 dBc Typical
Option 46: Auto power recovery
Disables the power switch on the front panel and automatically restores power after power failure.
Function
ON/OFF operation can be performed using the standby switch on the rear panel.
∗
Power switch on the front panel of this unit does not have a latching function. Therefore, if power is
interrupted in the ON status, the standby status is kept even after power is restored.
Option 47: Rack mount (IEC)
Function Mounts the rack mount for IEC standard-compatible rack. When mounted, the tilt handle (standard) is eliminated.
Option 48: Rack mount (JIS)
Function Mounts the rack mount for JIS standard-compatible rack. When mounted, the tilt handle (standard) is eliminated.
Option 23, 43, 44: Range expansion power meter function
Frequency range 100 kHz to 32 GHz ( Depends on the power sensor used )
Applicable power sensor
MA4601A (100 kHz to 5.5 GHz), MA4701A (10 MHz to 18 GHz),
MA4703A (50 MHz to 26.5 GHz), MA4705A (50 MHz to 32 GHz)
Power measurement range –30 to +20 dBm
Display Selectable from W, dBm, and dB (RELATIVE), Digital 4 digit display, 20% over range
Power range
5 range / 10 dB step (Measurement level range is listed on the power sensor specifications.)
full scale value: –20, –10, 0, +10, +20 (10 µW to 100 mW)
Range switching Auto, manual (settable to arbitrary range irrespective of range hold or input level)
Accuracy
±0.6% (W mode), ±0.026 dB (dBm mode, dB (RELATIVE) mode)
When including the zero drift in range1 (10 µW range) is as follows.
±1.2% (W mode), ±0.052 dB (dBm mode, dB (RELATIVE) mode)
Pressing ZERO ADJ key allows automatic adjustment to zero point.
Zero setting ±0.6% of full scale Typical value (10 µW range of maximum sensitivity)
Zero move between ranges ±0.2% of full scale (after zero setting at 10 µW range of maximum sensitivity)
Calibration oscillator frequency 50 MHz
Calibration oscillator level 1 mW ± 1.2% (for one year)
Averaging An average count can be set from 2 to 10.
