After you enter the ethernet address you want to use (i.e. 10.0.0.2) you must restart the unit on a live ethernet connection. You can use the crossover cable to connect to your computer's ethernet port as a live port, but only if you are assigning an address. If you use the DHCP (dynamic host control protocol), you must hook to a live ethernet connection that allows for DHCP requests.
On the instrument, use a Noise Marker. If you have a captured trace (in dBm) that you want to convert to dBm/Hz, use the following formula: dBm/Hz = dBm - 10 * log(1.03 * RBW)
No, the C/I measurement is intended for use when measuring Wi-Fi (802.11b,g and a) signals. The measurement makes certain assumptions about the nature of the Wi-Fi signal being measured and how it is affected by various types of interferers.
To do this measurement first measure the satellite carrier power. Using a marker, capture the peak of the CW signal to get that power level. Then turn the receiving dish a few degrees so it is aimed at deep space and measure the background noise level. We suggest using a fixed reference marker set at the peak of the CW carrier and a delta marker at the same frequency set to be a noise marker. By doing this, the delta marker value is in dB/Hz relative to the CW signal and once the receiving antenna is turned to deep space the answer can be read directly from the delta marker value.
The battery has internal circuitry that communicates with the main board on the Spectrum Master. Either the battery is defective or something in the Spectrum Master is failing to communicate. Please contact your local service center to have this issue resolved.
As of June 2009 the Remote commands for Quasi-Peak detection are being developed. They are not currently available. Expected date for these commands does not have an official target but we hope to have them by end of August, 2009.
After you set the MS2721B to the desired center frequency, make sure you don’t have any attenuation set on input port. Turn Marker one on. Select Peak Search. More Under Marker Style or Fixed Marker turn to fixed or on. Back Turn Delta ON for the marker one. You can change now the RF input level and will have the Delta value.
Currently Anritsu does not but is working diligently to provide a solution.
The GPS coordinates delivered by the instruments are based on the WGS-84 methodology of determining position.
Max. VSWR DC – 18 Ghz 1.06 + .005 fGhz Adapter, DC to 18 GHz, 50 Ohm, N(f)-SMA(f)
Yes it is supported. You can enter the frequency or you can select the signal standard and enter the channel number. Here are the signal standards: CDMA2000 Class 5 (NMT-450-20 kHz)- Uplink CDMA2000 Class 5 (NMT-450-20 kHz)- Downlink CDMA2000 Class 5 (NMT-450-25 kHz)- Uplink CDMA2000 Class 5 (NMT-450-25 kHz)- Downlink
Option 78 provides SFN measurements on a DVB-T/H SFN network to measure multi-path related issues. For modulation analysis and RF measurements, Option 64 is required, which does support 6 MHz DVB-T bandwidth. We've only heard of some trial DVB networks in the US which are no longer operational. However, please note that ATSC is the digital broadcast standard in the US.
Ec is defined as the chip energy for PCPICH and is determined by multiplying CPICH by the chip time. Ec = CPICH + 10*log10(Chip Time) or Ec = CPICH - 65.84dB
According to the WCDMA standard the chip rate is fixed at 3.84 Mcps, thus chip time can derived to be 0.26 micro seconds.
Press shift and trace keys, then select Trace A softkey menu, then select Max-Hold softkey.
Yes, the display data points are fixed and are independent of the Frequency Span and Resolution Bandwidth. There are 551 display points when the instrument is in the normal screen display. By selecting the Trace Fullscreen (On) feature the display point count increases to 661.
Yes, the MS2721B Spectrum Analyzer has quasi-peak detection function. Resolution bandwidth is 200 Hz, 9 kHz, and 120 KHz when quasi-peak detector is selected.
No, it is not possible to set more than 5 segmented limit lines on the MS2711D however we have other Handheld Spectrum Analyzers in which a limit line can consist of up to 40 segments. The model numbers are MS2721B, MS2723B, and MS2724B.
To erase all the user information that is stored in Internal Flash Memory and EEPROM, a master reset needs to be done on the instrument. Below is the master reset procedure.: 1. Turn the MS2724B. 2. Press the Shift button then the 8/System button. 3. Press the System Options soft key. 4. Press the Reset soft key. 5. Press the Master Reset soft key. 6. A dialog box will be displayed on the instruments screen warning that all settings will be returned to factory default values and all user files will be deleted. 7. Press the ENTER button to complete the master reset. 8. After several seconds (which can grow to several minutes if there are a very large number of measurements saved in the instrument) the instrument will reboot.
Yes you can. You can go into the sweep menu (MT8222A, MS272XB) or "MEAS/DISP" menu (MS2711D, S332D, S312D, MT8212B) and select "Min Sweep Time" and enter the desired sweep time. If you enter a time that is faster than what the instrument is capable of then the instrument will change the sweep speed and default to whatever the instrument can do. For every measurement point, the instrument spends a certain time and if it is too fast, then it is measured again. This is why the actual sweep time is usually a little bit longer than the requested time. In zero span mode, the sweep times are exact.
